Merry Christmas to all on here. I have lurked on here for years and have enjoyed reading about all of the interesting muscle cars...great website! My favorites are always the barn and garage finds, and I now have one of my own to post on here.

But it isn't the typical muscle car, and you have to look past its number of doors to truly understand its historical significance. It is a plain jane gold 4-door, granny-looking car that was the 2nd Nova police car ever built, and its build sheet says "COPO OPTIONS". It was ordered by an executive named Rick Mahoney who was the Fleet Sales Manager at Chevrolet's Los Angeles Zone Office. In addition to the build sheet, I also have the envelope that held the car's speedometer certification paper (which has the car's VIN typed in), and the warranty booklet which has "Zone 20 Demo" typed on the bottom (that is the number of the LA ZO). The speedo cert envelope has a return address for "Chevrolet Motor Division. Los Angeles Zone", and is addressed in the lower right corner to "R. Mahoney" and references "CFH-453", which is the car's order number from its build sheet (that is how Chevrolet kept track of its zone office cars).

I am friends with a nice gentleman named Harry Hammond, who was one of the 2 engineers that GM brass tasked with building a Nova police car prototype in Jan. '74. Harry is now retired from GM, where he ran its 9C1 and B4C police car programs from 1974-2001. He has provided a wealth of information regarding my car, as well as the 4th Gen Nova police cars which were produced from 1975-78 (approximately 15,000 were built). Harry assisted Rick Mahoney in ordering my car...they filled out its order form on the kitchen table at Rick's home in Northridge, CA, and it was ordered, built at the Van Nuys GM plant, and delivered to Rick in just 2 weeks!

The purpose of the Nova police car was to build a usable police car that could achieve good gas mileage and perform all of the necessary tasks that larger police cars could do. At that time, the US was going through the OPEC Oil Crisis, which occurred when Middle Eastern countries doubled the price of the oil they were selling to the US, and also reduced exports to the US. Police agencies were looking for an alternative to the gas hog police cars they were driving then, and a Motor Trend magazine editor named John Christie suggested to GM that they combine a Nova with a Camaro to create a police car suitable for the times. John Christie's office was located in Los Angeles, and he was a reserve deputy for the LA Sheriff Dept, which was (and is) the largest sheriff dept in the US. He knew the LASD was preparing to conduct police car tests in late April at the LA County Fairgrounds in Pomona, and that Chevy had an opportunity to get in on those tests. He also knew that those tests would provide an opportunity for him to write an interesting magazine article or two.

Harry received a mechanical engineering degree from Mich State, and went to work at the GM Tech Center on Van Dyke Blvd in Warren (north suburban Detroit) immediately after graduation. The first project he worked on was building 2 taxicab prototypes for evaluation by the NYC Taxi Commission...one was yellow, and one was white. The Nova police car prototype was his 2nd project.

A 2nd GM engineer named Jim Ingle was borrowed from the F-Body Program office to assist with the police car. Jim was an assistant to Vince Piggins, the father of the Z28, and his specialty was suspension engineering.

Harry and Jim took the white '73 Nova 4-door taxicab that was languishing in the Tech Center's parking lot and brought it into a room and yanked its 6-cylinder drivetrain. The taxi had tinted glass, A/C, a plain taxi interior with a rubber floor mat, and it was a perfect platform for the police car. Harry and Jim put together a laundry list of GM parts numbers needed for the project and obtained them from one of GM's many Detroit warehouses. The police car took about 2 weeks for the mechanics that were also on the police car team to build. Then the fine tuning began. GM's Proving Ground is located in nearby Milford, and contains a huge asphalt parking lot named "Black Lake", due to its resemblance to an actual lake. The engineers tried every combination of springs, shocks, bushings, sway bars, wheels and tires to come up with the best possible result. One of the hardest areas to address was the Nova's tendency to tip during high-speed directional transitions. That test occurred when the car was going 45 mph and was turned in a 90 degree direction. Jim suggested that the 14x7 wheels used on the '69 COPO Camaro in conjunction with wider bias-ply tires might achieve the desired results and stop the tipping, and he was right.

The rest of the prototype was standard GM fare...an L48 350 4-barrel engine, TH350 transmission (but with a special high-speed shift valve and a heavier-duty torque converter), a dual snorkel air cleaner borrowed from the Z28, a Z28 4-spoke steering wheel, dual exhaust, an HD radiator, a 3.08 posi axle, an HD alternator, power steering which utilized a Z28 steering box, and front disk brakes. The rear brakes were borrowed from a Chevelle station wagon as the drums had larger cooling fins and larger shoes to handle repetitive high-speed stops.

Harry and Jim left Detroit on Thursday April 25th and drove their little white sleeper to LA, utilizing as many back highways as possible to evaluate their creation. They spent the first night at a motel in Joplin, MO, their 2nd night in Tucumcari, NM, and their 3rd at a hotel in Santa Monica.

The prototype surprised and pleased the LASD officials, and easily bested the Plymouth Satellite, Dodge Coronet, and AMC Matador that it was designed to beat. It also beat Mopar's smaller entry, a Dodge Dart with a 360 4-barrel, and a Pontiac Ventura with a 350 4-barrel Pontiac engine (none of the competitors got better that 13 mpg...the Nova got 16.1 mpg on the 72 mile urban test-loop that involved both freeway and city streets).

Also present for all 3 days of tests (April 29th-May 1) was Rick Mahoney, and he knew he needed a demonstrator Nova of his own. The day after the tests, Harry, Jim, and Rick held a meeting at the LA Zone Office with LASD officials to discuss ordering Nova police cars. Harry suggested that the LASD should wait until August to order the new 4th Gen Nova police car, as it had a larger interior (the 3rd Gen Nova's biggest drawback...lack of backseat room for prisoners), and was a better-engineered car (the 3rd Gen police car was a rush job, and Harry knew it). The LASD decided to order 11 '74s for further evaluation, and the City of Fountain Valley PD ordered 4 more (the chief of police in FV was a close personal friend of Pete Pitchess, the commander of the LASD, and he had heard about the great new Nova police car and wanted in on the action). Rick invited Harry and Jim to his house in Northridge for a BBQ on Friday evening, and the gold Nova police car demonstrator (my car) was ordered while the men shared drinks at the kitchen table.

Rick kept the car until Nov. 4, 1974, which I can verify by its original warranty booklet, which miraculously stayed with the car (along with its speedometer cert paper). The warranty book is actually for a '75 Chevrolet, and Harry believes this was because zone offices typically got rid of all of the previous year's papers upon the start of a new model year. The buyer of the car was the "County of Los Angeles, Fleet Management Division", and the car was assigned the number "46892", which is painted into the driver's door jamb area. The car's keys are stamped "LASD 46892", and also "STA 9", which was the West Hollywood station back then. The mileage at the time the zone office got rid of it was 2,169. The car also has a shotgun rack still riveted to the right side of the trunk...it contains a locking mechanism which releases the gun when a toggle switch hidden under the dash applies 12 volts. Inside the glovebox is a yellowed sticker which identifies the 4 radio channels that the car communicated with...the first is "WHD Disp" (West Hollywood Dispatch).

I found out about the car in June 2017 when a woman named Nancy Smith sent me an email that her 86 yr-old father, Woodward "Woody" Smith had Alzheimer's Disease, and she needed to sell his house in the Hollywood Hills (his house was on Holly Drive, right behind and up the hill from the historic Hollywood Bowl amphitheater). Inside his garage was a gold Nova that he had always told his kids was an actual police car. Nancy had tossed around the idea of having the car hauled off for junk, but thought it might be worth more than the $200 she had been offered for it. I told her to have a mechanic pull out the back seat or lower the gas tank to see if the car's build sheet could be found (it was on top of the gas tank). As soon as I saw "COPO OPTIONS" on the sheet, I told her I wanted to buy it. We settled on a price for the non-running car, and I told her I would be in LA within 30 days to buy it.

The car was absolutely pristine, just dirty from sitting inside a garage for 31 years. Woody was a compulsive pack rat and had saved every piece of paperwork that had come with the car, as well as all of the papers and receipts for the 4 other '75-78 Nova police cars that he had purchased at LA County auctions (he gave one to each of his kids for use at nearby Hollywood High School...yes, the same Hollywood High from countless movies and TV shows). It was while going through the papers that I discovered the speedometer cert and warranty booklet that confirmed the history of this unusual and historic car. Also with the documents was the LA County auction receipt from April 24, 1982 where Woody bought the car for $875. The sales receipt shows that the LA Co. agency getting rid of the car was the LASD, and that its county vehicle number was "46892".

After 8 wonderful days visiting LA with my best friend, Dave Blumberg (we had both been stationed on ships at the Long Beach CA Naval Station in the early '80s), we headed back to my house in Columbus, OH with the cop car.

Once I started looking the car over, I realized what a little gem it was. I has one minor rust area on the right front door, and a couple of dents, but nothing major. I cleaned the car out by removing both seats and discovered many matchbooks which included one for a Hollywood strip club (cops!), a Hollywood liquor store (cops again!), and a couple of diners (Bob's Big Boy and Norm's...both well-known LA institutions). Also found were many cigarette butts, a couple of .38 caliber shell casings, a couple of crumpled cigarette packs, a Moon Pie wrapper, an orange plastic key fob for the LA Zone Office, and a money clip for the LA Zone Office with the initials "RM" engraved on it.

I found Rick Mahoney's sons once Harry told me that Rick's actual name was Wilbur B. Mahoney...he was the only man by that name in the state of California. Rick's son Bill lives in beautiful Cambria, CA, just south of the Hearst Castle along scenic California highway 1. He was 16 when his dad brought the gold Nova home, and he said it was a very fast car that his dad was very proud of. His dad liked to race people at stoplights...it was the perfect sleeper. I am having the money clip duplicated by a guy in Florida and will give copies to Bill and his brother Scott...the original will stay with the car.

I got the car running by replacing its varnish-filled gas tank, replacing its fuel pump, cleaning out its clogged fuel lines, and having its original Q-jet carb rebuilt. I towed it up to Fenton, MI so Harry could see the car he designed and ordered. We shared a burger and a couple of drinks at his country club, and he gave me several police car books and GM documents that related to the design and building of the police car prototype. He also signed the inside of the trunk lid...I am deeply honored.

I towed the car to the Nova and GM Nationals in July 2018, and it rained nearly the entire weekend. There were many spaces available under the Nova pavilion, but I was told "No" when I requested a dry place to park (guess what...I won't return). Next to the Nova pavilion was a bldg. and tent that the Super Car Workshop from Latrobe, PA had rented to display the LS6 Chevelles, Corvettes, COPO and Yenko Camaros, and Yenko Novas it had restored. One of the guys standing at the doorway of the SCW bldg. was well-known author and Chevy muscle car expert Phil Borris. He noticed my soaked Nova with its 3 large display boards, dog-dish hubcaps, and wide steel wheels and came over to see the car. He immediately invited my car into the SCW tent to sit alongside the expensive Chevy muscle cars. Many guys came over to look at it, and it received favorable comments. Phil noticed its Z28 dual snorkel air cleaner (which is shown on the build sheet), and also noted its 8" harmonic balancer and that the engine had a non-L48 camshaft (he thinks it has an L82 cam as it has a somewhat lumpy idle...not as smooth as an L48's).

He invited noted muscle car expert and writer, Drew Hardin from Muscle car review magazine to look at the car. Drew spent 30 minutes photographing it and taking notes on it. Drew said he had never seen anything quite like the Nova, and was especially impressed with the envelope which showed it was a Brass Hat car. He put a sidebar on the car on p37 of the Oct 2018 issue of Muscle Car review, and indicated he would like to do a feature on it at some point in the future.

I took the car to a large, nationally-recognized show in Columbus, the Len Immke Memorial Classic Car Show in August, and one of the judges saw its paperwork. He asked if I would take him for a ride, and he was very impressed by its acceleration (in spite of its smoking engine and poor compression numbers, it still has great acceleration). He classified it as an unrestored muscle car, and it won 1st place at the show, beating 15 competitors.

For the time being, I plan to keep it unrestored. Its body is pretty beat-up, and there is no saving the roached paint. I had the left valve cover off 4 months ago to replace a very leaky gasket and discovered that it has Z28 heads (numbered "330545") with screw-in rocker studs and high RPM push rod guides, which are definitely not stock L48 heads. Harry Hammond thought that Rick may have had some mods done to the engine to make it faster for demonstrations for police officials, but he couldn't confirm this. It will be rebuilt this winter, and I'll be taking it to the Heartland Nova Show in the Quad Cities in June. The club president, Jeff Grady said it would be allowed in their pavilion in case it rains. ;-)

Thanks to all. Yes, that is the original air cleaner. It has a painted top instead of a Z28's chrome top, but is otherwise identical. The build sheet's air cleaner box has a "DY" code, but the sticker on the side of the air cleaner is "DW" (it's the very faded original sticker...not a reproduction). One of the guys at the Super Car Workshop bldg. in Carlisle said there were 2 versions of the dual snorkel air cleaner in '74...one for a points-type distributor (DW code), and one for an HEI distributor (DY code). My car was probably one of the last to get the points distributor, hence the switch to the points-style air cleaner which had a smaller indentation in the back than the HEI air cleaner. Harry Hammond said the L48 Nova's single snorkel air cleaner was starving the carburetor for air at maximum throttle, so he used the Z28's dual snorkel air cleaner to solve the problem. The right exhaust manifold on the engine has a provision for a heat tube to an L48 air cleaner, but since the Z28 air cleaner did not use a heat tube the heat stove sits on the manifold without a purpose.

The last photo in the first group of photos is Rick Mahoney presenting the first Nova police car to Lt. Bill Kirtley at the LASD headquarters in mid-June 1974. It's hard to see, but the car wears Goodyear Polyglas E70-14 raised white-letter tires. My car still has its original Polyglas RWL spare...the same tire as delivered on all 17 '74 Nova police cars. The 15 police cars ordered by the LASD and the City of Fountain Valley did not have 350 engine badges like the white prototype and the gold demonstrator because the police didn't want them.

The top 3 photos in the second group of photos are of Harry Hammond seeing the car at his country club in Fenton, MI in July 2018. The next 2 are Drew Hardin of Muscle Car Review magazine photographing the car, and the last 2 show the car car wearing its new reproduction Goodyear Polyglas RWL tires. The gas station in the next-to-last photo dates back to 1929 and is still owned by the same family that built it on a small state highway about 25 miles north of Columbus, OH.

Very cool. Nice that you saved it and have documented it so thoroughly.

I drove a 6-cylinder 4-door Nova in high school driver's ed back in 1974. I sure wish it had been this car instead but I would have probably gotten myself in trouble.

67Z28, I also went through driver's ed in '74, so we are probably the same age (I just turned 61). My driver's ed car was a white '74 LTD that was a real land barge to learn in. It had signs on the sides advertising Charles Gabus Ford in Des Moines, IA...the good old days.

The only reason that I know what this car is, is due to its documents staying with it (and my friendship with Harry Hammond...he has been a great source of info on the prototype and this car).

I am 60 and started driver's ed in fall of '74 and you probably were in the spring. I started in the Nova and later had to switch to a 4-door Malibu which I also felt was a land barge. Definitely preferred the Nova.

Jon, I knew I had seen your '67 Z before. I read about it recently in a muscle car magazine (MCR?) that it was the first '67 Z28 built, and that you basically found it by sheer luck. I'll have to dig through my stack of muscle car mags and find the article.

Just like you, I found my Nova through luck/fate, and like yours it is a very historic car. Unfortunately, it is a 4-door and gets hardly a second glance at shows. I believe it is probably the best documented Chevy police car in existence, and possibly the most historic. The 4th Gen Nova police cars are generally considered to be one of the 10 greatest police cars of all time, and this is the only 3rd Gen known to exist. Should I restore the beat-up body with its mismatched paint, or just drive/enjoy it like it is? A good paint job will probably run at least $7,500-$10k, and I'm not sure I would enjoy it any more. It has great patina, and I don't really care about accolades for it.

Is it best to leave it alone? I would appreciate your opinion.

1967Z28
12-26-2018, 07:41 PM
I don't think I would go hog wild trying to restore it. There is some value in having it in kind of an untouched state. With that said, I do really like the dog dish hub caps and the Polyglas tires that you've put back on it. Have you had somebody attempt to buff it to bring more life to the paint? It might be nice to have the hood paint more closely match the rest of it but you'd have to know a pretty talented painter to get it to match the rest of the patina. It would not seem to make sense from an investment standpoint to pour a lot of money into the car. If you did a show-worthy restoration it would have to be because you felt a personal calling to do so. That's how I see it.

Jon, thanks for the advice...much appreciated. The car obviously had the hood repainted (and poorly) at some point during its time with the LASD, and it's the biggest drawback to its appearance. I have the money for a paint job, but I think it wouldn't generate much more interest (and it might actually generate less...it's a flip of a coin).

The engine is badly in need of a rebuild as it smokes for 10 minutes upon startup, then most of the smoke goes away except under full throttle applications (it still easily turns the tires over, but I don't want to damage the engine, so those are few and far between). The compression runs from 110-85, and I know the rings are shot. The car was built with an L48 (shown on the build sheet), but somewhere along the way it picked up the Z28 heads, a lumpier cam that sounds just like an L82's, and the beefy harmonic balancer. Harry said that Rick Mahoney was well known among the Chevy higher-ups for doing mods to the Zone Office cars, and thinks he had a buddy (service manager Bill Johnson) at Arrow Chevrolet (the LA dealership that Rick liked to have his cars delivered to...this car was delivered there), do some mods to the car to make it quicker...adding Z28 engine parts would've accomplished that task. California was very sticky about changes to engines due to its strict air quality standards (even back then), and installing a Z28 engine at the factory would not have been allowed (that engine was not certified for use in a Nova, and it would've been cost-prohibitive for GM to do so). The '70 Z28's LT1 was installed in Novas to create the Yenko Nova through the COPO ordering process, but that was no longer allowed by 1974. I think Rick found a way around it by having the parts installed at a Chevy dealership and then keeping quiet about it. His number one goal was to get the LASD (and other Socal law enforcement agencies) to buy Nova cop cars instead of the Dodge Coronets, Plymouth Satellites, and AMC Matadors they were used to buying (all powered by 400-401 cubic-inch engines...4-door muscle cars), and knew he needed something that would generate some thrills with the cops going on demonstration drives...what better way to do that than with a high-rpm Z engine?

It's a shame that the car doesn't generate more interest, but it's really just emerging from its 31 year slumber, and I have only had it to a couple of shows. Phil Borris at the SCW tent at Carlisle said it would probably be welcomed at the MCACN, and I will try to get it to Chicago for the 2019 show next Nov. Most Nova people don't really understand the historical significance of the car and only make comments about the seemingly incorrect parts on it (like its air cleaner), not realizing that it's a COPO and that's why its odd parts are there. It has received very few comments on here, probably due to its 4-doors (just a guess).

Best regards,
Alex Manz

You are not too far from KY. Get the engine rebuilt and bring it to Bowling Green KY. for the Super Car Reunion in July and have some fun with it. There will be people there who will appreciate it for what it is.

I do really like the dog dish hub caps and the Polyglas tires

didn't all '74 Chevies come with radial tires? i worked at a Chevy dealer through most of the 70's and i remember radials on all the '74 and later models. :dunno:

9C1Beater

Hey Paul and Burd...good to see you on here. Bruce Hamilton sent me a copy of "Bone Stock and Modified" (an AWESOME Canadian magazine that I wish I could find here in the States) which had an article about your Bullitt '68 440 RT Charger...an incredible car! And Burd...it's always good to hear from you, even though you didn't call me back a few days ago as you said you would....shame!

In answer to the comment about radial tires on '74s...that's an interesting one, and I can answer it. My good friend Harry Hammond from the Nova 9C1 program and builder of the '74 Nova police car prototype, said that he wanted to put radials on that car, but there was an incident that halted that...the death of an Alabama Highway Trooper in late '73 (I don't know the exact date of the accident) that happened when one of the Firestone 500 steel-belted radials on his patrol car suffered a belt separation at a speed around 120 mph, which caused the car to crash into a steel bridge and killed him instantly. GM immediately put a halt to installing Firestone 500s on their cars for several months (I believe Harry said it was sometime around Jan or Feb '74), and Firestone issued a nationwide recall of the tires. The fallout from the trooper's death affected the sales of other Firestone tires, and GM put mostly Goodyear, Uniroyal, and General tires on the remaining '74s. My car came with Goodyear Polyglas E70-14 raised white letter tires (the build sheet shows option "QEB E70-14 LT" for lettered tires...see above photo near the start of this thread). Harry said the bias-ply tires didn't handle as well as the new radials, but he knew they could handle punishing abuse which causes heat (heat was the cause of the Firestone 500 steel belts separating). Firestone put a rush on developing the 125 Kevlar-belted radials, which were ready for installation on the 4th Gen Nova 9C1 police cars in the fall of 1975. The Kevlar-belted tires had no heat-related belt issues.

My car looks a little odd with the RWL tires, but it still has its original spare which matches the repop tires now on the car. It is probably the only '74 4-door Nova in existence which came originally with those tires.

And Big Gear Head, I think I just might drive down to Bowling Green for that show. My Nova isn't really worth a whole lot of money (it isn't a Yenko COPO), and I don't intend to throw a lot of money at it, so it would be fun to see what it could do on the strip.

And for those of you who don't know this, Burd started a website called "UnitedFBody.com", which is an excellent site full of inappropriate jokes, innuendos, and a little bit of actual car-related stuff. He was originally going to call it the Firebirds United with Camaros Club, but realized that its abbreviation was somewhat questionable.

I know I have them, but I just have to look. When the local Chevy dealer building was sold here (it closed in 1982) I got to go through what was left. One thing I found in a filing cabinet was trade in pictures of my towns police cars, which two were Novas. I remember the cops at the time all fought over who was going to drive them because they all raved about them...

Igo...I would like to see the photos of the 9C1 Novas. I have posted a ton of stuff about them over on Steves Nova Site (SNS) in the Registry I created for them.

I bought a '77 Nova 9C1 for $400 five years ago after spotting it on CL-Phoenix, and flew out from Columbus 3 days later to buy it from a young Hispanic guy who had been given the car by an older guy he did landscaping for. Its beat-up condition is how I got my nickname "9C1 Beater". I found the build sheet for it above the gas tank and posted a lot of info on that car (and many other real 9C1 Novas). There was very little info on Nova 9C1s on the Internet prior to the Registry, and much of it was flat-out wrong. Plus, no one really knew how many were left, so I decided the best way to figure that out was listing every single one known to exist. I found Harry Hammond in Fenton, MI through an Internet search and got a lot of info from him...a great guy. There are now 21 4th Gen 9C1 Novas, and one 3rd Gen in the Registry...it is the best resource on the Internet for info on these rare and special cars. They are considered by most police car aficionados to be the greatest Chevy police car ever built.

It was because of the Registry that Woody Smith's daughter Nancy notified me about the existence of her dad's gold '74 Nova police car. It is the earliest Nova police car known to exist...the only 3rd Gen survivor out of 17 built. I plan to list all of its special engine and suspension parts in here. It seems to generate more interest on here than on SNS.

My '74 Chevelle has the police package, and came with HR70-15 Goodyear "Blue Dot" pursuit tires (RPO QQZ) mounted on 8" wide Corvette rally wheels. They had a thin white stripe sidewall.

Keith...that sounds like an awesome car! Any Chevy cop car from 1974 is rare. Most were Belaires, and I think I've only seen one photo of a Chevelle cop car. You can hijack this thread and post pics and info on here. What engine and options does it have, where was it used, and what condition is it in? Does it still have its original Blue Dot spare? Those tires would be impossible to find now, I'm sure.

Harry Hammond said that he and Jim Ingle were under the gun time-wise to build the Nova police car prototype. They were given the job around the middle of Jan '74, and the LASD wanted any cars that were going to enter the '74 police car tests to be ready by the end of Feb (I don't know why that was a stipulation, but it was). The ban on radial tires for police use was a hit on the car's performance, but not a big one, as it still was able to generate .8 Gs on the skid pad at the GM Proving Grounds. After the Feb deadline passed, they had another 2 months to play around with the suspension and dial it in as best they could. The photo from the beginning of this post shows the Prototype at the skid pad at Black Lake and the car is relatively flat on a high speed turn. Harry said the car handled like a Z28...it was essentially a 4-door Z28.

My car still has all of its F41 stuff underneath, and it's all in good shape. It also has some factory paper stickers from the assembly line in place (the result of being from sunny LA). The rubber bushings are shot and will be replaced this winter. The bushings are identical to a Z28's, but I think the rear sway bar is slightly different.

My dad ordered it for my Mom to drive. He found out the police package was available on the base Malibu so he checked all the boxes.

They didn't want to build a two door at first, so the order got rejected. He called Central Office and reminded them that it showed as available in their literature and he thought they should build it as ordered. They relented and put the order back in the system.

He ordered it with the same interior as our '73 Monte Carlo: black and grey herringbone weave with swivel buckets and the rally dash. They bounced it again because of the interior. He called 'em back and showed them in the engineering summary that all of those options were available. So they relented and put it back in the queue.

After another delay they called to tell him which week the car was going to be built. Somehow he knew during that timeframe that they were only building hardtops with the small opera window and he wanted the large window. When he called to complain they finally said "Fine. Here's the guy's name in Oshawa. Just call him and tell him what you want."

So he did.

It was built in late September of 1973. It's a 454/TH400, 3.42 posi. Came with HD alternator and front and rear swaybars, and the aforementioned 8" wide Corvette rallys. PS/PB, non AC, manual windows and locks.

Mom drove it four years and I got it after that. I don't have any photos from the beginning but pictures of the car started cropping up around 1978 when I started driving it.

As of 2018 I have been racing this same car for 40 years.

Harry Hammond said that he and Jim Ingle were under the gun time-wise to build the Nova police car prototype.

I don't know Harry but I have worked with Jim Ingle.

He was a famous Corvette development engineer at the time; I don't know how I weaseled it but somehow I was on a Corvette ride trip and did a rotation or two with him in the passenger seat.

The thing about Corvettes is, since they only seat two, you can have some really good intimate conversations for 1/2 hour or 45 minutes at a crack.

He said to me "...you know, I'm actually kinda jealous of you truck guys..."

Here he is, a GM development engineer on the CORVETTE programs, so I said "Jim, why would you say that?"

He replied "People NEED trucks; people don't really need Corvettes.

Keith...wow, what a car and what history! I am reading between the lines here, so I assume your dad was a GM employee...possibly at the Tech Center in Warren? And then did you go to work for GM?...that's how I figure you got to go for a ride-along with Jim Ingle (even though you were driving). Glad to see you were smart enough to hang on to such a rare and cool car with family history. If your dad was connected high up at GM, then he could pretty much get whatever he wanted.

I have some questions about my Nova's engine, but Harry says he can't answer them. I know from the build sheet that it was ordered with a 350 L48, which is the same engine that the '74 Nova police car prototype had when the LASD police car test were done in May '74. My car still has the numbers matching engine, but it has Z28 heads that have the part number 330545., and it doesn't have a stock, smooth L48 cam. I know that The LA Sheriff Dept and the first civilian owner, Hollywood film editor Woody Smith didn't do changes to the motor, so that leaves Rick Mahoney, the LA Zone Office's Fleet Sales Manager. Was it common for Chevy execs to skirt the GM rules and build engines that weren't within corporate guidelines? Harry Hammond said he didn't think the engine would've been built by Flint, and he said he was unaware of the mods. I'm in the process of pulling the engine out and will post photos on here of what I find. I know this is a very strange car, and it is an important part of Chevy's police car history. Also, before I forget, Harry said Jim was no slouch in the driving department...he did a lot of the driving of the Nova police car prototype at the Proving Grounds.

Thanks for posting the photos...much appreciated!

PS...Igo, no big deal, but I'd like to see them if you find them. Thanks

Good reading here. Beater, you gotta come up and see the Gold Nova at the Heritage center. Of all the cars in there, I fell in love with it. It has a 4 speed, and I’m a dog dish guy. It has them.
Of all the cars, I had to get in it, I asked Greg and he let me get in it. I have a pic somewhere, but I’m having issues posting pics here :/

Thank you; we tend to hang on to stuff in my family -

Dad worked for GM for just over 30 years, as a die maker for Chevrolet Pressed Metal division (in Flint) and then as an Advanced Manufacturing Engineer for CPC (Chevrolet-Pontiac-GM of Canada, in Pontiac). He is the GM patentholder for some cool inventions like hydroforming, laminated steels and adhesive bonding of aluminum space frames.

He also raced for Pontiac Motor Division through the Royal Pontiac dealership. You can read about that here if you are interested:

The GTO is presently anchoring a special muscle car display in the Gilmore Museum (Hickory Corners MI) through this April.

I'm just shy of 40 years with GM in vehicle assembly and product design/development. I started at the Chevrolet assembly plant building trucks in 1979, worked at the Milford Proving Ground from 1986 through 1990 and the Desert Proving Ground from 1990 to 1994, which is where I was when I met Jim. I've been in product design, engineering program management and, most recently on an off property special project, since that time.

Wow Keith...I'm honored to have you comment on my Nova. Thanks for sharing your family's GM history...impressive! If you have been with GM for 40 years, then I'm guessing retirement isn't too far away. I hope your dad is still around and in good health.

If it's possible, I would really like to get in touch with Jim Ingle and let him know that the 2nd Nova cop car ever built still exists, and I'd even be willing to drive the 3 hrs from Columbus to Detroit to let him drive it. I would like to get his signature on the trunk lid next to harry Hammond's! I would also like to let the GM Heritage Center know about the car, and I'd be willing to let them display it sometime. It has a ton of documentation and photos which explain its complete history. If you could point me in the right direction to talk to someone there, I'd really appreciate it.

Also, I talked to Roger Burd, and I think he knows you. He mentioned it would be great for the 3 of us (and a few other GM car nuts) to get together at Dugan's (sp?) on Woodward Ave for an evening of beer and wings. I have his number if you need it. He's a real hoot to talk to.

Jim suggested that the 14x7 wheels used on the '69 COPO Camaro in conjunction with wider bias-ply tires might achieve the desired results and stop the tipping, and he was right.
14x7 wheels were just standard 69 SS wheels and used on 100's of thousands of newer cars in the 70's. What size came stock on 74 Novas?

Get the car to someone who knows paint and they can save it.

What's the dates on the heads? What's stamped on the engine pad?

Kurt, thanks for the reply. I know you're big in the Camaro world. I was on CRG for awhile with a rusty red '69 Camaro Coupe which had its original 250 6-banger and a 3-on-the-tree shifter...sold it due to the insane amount of rust on the body. My plan was to restore it the way it was built...dog-dish hubcaps and radio delete.

About those 14x7 inch wheels...they were not available on '74 non-SS Novas, period. Attached is a letter Harry Hammond gave me dated Mar. 21, 1973 where he is explaining to "W. B. Mahoney" (Rick Mahoney...the GM exec at the LA Zone Office who ordered the gold Nova that I now own) that Jim Ingle suggests that Rick install E70-14 bias-ply tires on 14x6 Chevelle station wagon wheels to get the 4-door Nova he was working on to handle better. You will note that the letter's subject is "Nova Police Demonstrator", and it is dated a full year before Harry and Jim built the "officially" sanctioned GM Nova police car prototype. Harry told me that Rick Mahoney was trying to build a Nova police demonstrator using a Nova 4-door ordered with as many high performance options as he could...350 4-barrel, TH350, power front disk brakes, F41 suspension, posi rear axle, and HD cooling. Harry and Jim were providing tips to Rick on what parts to change in order to achieve the best outcome, and they even flew to LA to attend the tests in the spring of '73. Unfortunately, Harry said the car was not up to the handling and braking criteria set forth by LASD officials, and they declined to purchase any. But Harry said that everyone involved could see the plucky Nova's potential, and Rick spoke to John Christy about pushing Chevy to build a real contender. I don't know if it was John Christy who was the brainchild for the Nova police car, or Rick Mahoney...I think both of them deserve credit.

Also attached is John Christy's letter to Jim Williams, a Chevrolet executive who unfortunately passed away this past March from cancer. Harry said that I was the first person he had given this letter to. Previously, it was known that John Christy, an editor and writer for Motor Trend magazine had written to Chevrolet, but the contents of the letter were unknown. The letter is dated Jan. 16, 1974 and is asking Chevrolet to provide a smaller-sized police car prototype for testing in the upcoming 1974 LASD Police Car Tests. It gives very specific criteria regarding the vehicle's size...only the Nova fit those size restrictions. It also says that the prototype should be completed by Feb. 28th...about 5 1/2 weeks for Harry and Jim to build a useable prototype...not much time! They had the basic car ready for testing about 2 weeks after the letter was received, and they then spent the next 2 months fine-tuning it on the skidpad at Black Lake (Milford) to dial it in. I took my Nova on a twisty country road SE of Columbus in the scenic Hocking Hills (where Car and Driver liked to test their cars many years ago), and it handles like a sports car!

You will note that one of the guys who received a copy of the first letter was "D. R. McClellan", who took over the Corvette program after Zora Arkus Duntov retired in 1975. Dave McClellan ran the Corvette program until 1997, and he was inducted into the Corvette Hall of Fame in 1999.

It's funny, but all of these big gearhead engineers at the GM Tech Center were trying to get the Nova to handle well, and yet none of them thought to upgrade to 14x7 inch wheels! Harry said that at that time, the largest wheel that could be ordered on a 4-door Nova was a 14x6 (14x7s were available only on the SS), and they didn't really think about what other wheels were available in the GM parts bin. The biggest problem with the Nova 4-door was its high center of gravity, and it took quite a bit of experimentation with springs, bushings, shocks, amd wheels to get it to handle like a Z28. You will also note that the letter says that the rear spring eye bushing for a Z28 should be used to help control axle wheel hop, and to use Chevelle rear brake drums. Eventually, the brake drums from a full-size Chevy were used (my car has them) in order to achieve the best results. Harry said their benchmark for testing was the Plymouth Satellite police car, which was essentially a 4-door Road Runner. Harry said that Vince Piggins had some input on the Nova police car prototype (he thinks it was Vince's suggestion to use the Camaro's 14x7 wheels...this was at a time when not many GM cars used those wheels), but he couldn't find any documents which were addressed to him (Harry was only able to keep a small amount of papers when he left GM at retirement, and must of the documents were tossed out because "we couldn't save everything!").

I have been active in the Nova 9C1 police car community for 5 years (I started the Registry for them), and this is the only currently known 3rd Gen Nova police car in existence of the 17 ordered (plus the prototype...whereabouts unknown). It was the 2nd Nova police car ever built, and it was ordered by a GM executive, built at the Van Nuys plant, and delivered to him in only 2 weeks. It is the only COPO 3rd Gen Nova 4-door I am aware of (it says "COPO" on its build sheet). It is the only F41-equipped 4-door '74 Nova I am aware of. It is the only 1974 Nova I know of which has a dual snorkel Z28 air cleaner. It is the only '74 Nova 4-door I am aware of which came with raised white-letter tires (on its build sheet), and came with 14x7 plain steel wheels (coded "EM" on its build sheet). It is the only posi-rear equipped 4-door '74 Nova I am aware of (G80 coded on its build sheet). It is the only Chevy of any kind I am aware of which has a document from Chevrolet Motor Division which states that it is a "Brass Hat" car (which I believe indicates it's something special...see document I posted at the beginning of this thread). It has deep documentation and has been verified by the father of the Nova police car program, Harry Hammond (he signed its trunk lid). Found in the car during cleaning was a money clip from the Los Angeles Zone Office with the intitials "RM" engraved upon it...Rick Mahoney's money clip. Following its 5 1/2 months as a police car demonstrator at the Los Angeles Zone Office, it was purchased by LA County and used as an undercover car for 8 1/2 years at the West Hollywood station (verified by a sticker in its glovebox and stampings on its keys), and it still has a shotgun rack riveted to its trunk floor. It was purchased for $875 by a Hollywood film editor named Woodward Smith at an LA Co. vehicle auction in April 1982 (I have the auction paperwork), driven by him for only 3 years, then stored in the garage under his home in the Hollywood Hills for the next 31 years until I purchased it. It has deep Chevrolet and law enforcement history, and I hope it becomes recognized for it.

I hope to display the car at the 2019 MCACN. Best regards, Alex Manz

I also wanted to post a few photos of the cylinder head I removed from the driver's side of the Nova's engine. It has the part number "330545" and is dated "A293', which I believe means it was made on Jan 29, 1973. The engine's pad bears the letters "CKD", and I couldn't get enough oil of the rest of the pad to make out the rest of the characters (my can of brake cleaner ran out...I'll get back to you with the rest of the info when I can). The build sheet says it was ordered with an L48 350 4-BBL, and is also coded "KD" in the box for engine code. The prototype '74 Nova cop car was built with a 350 4-barrel, and so was this one (they are identical cars except for the color). But somewhere along the line the car picked up some engine mods, and I believe they were installed by Rick Mahoney. He was the fleet sales manager for the LA Zone Office, and it was he who would be taking police car buying officials on high speed joy rides to persuade them to buy Nova cop cars instead of Mopars or AMCs. I am in the process of puling the engine and will photo document every item I find. I think Rick built a "ringer", just like Smokey Yunick or Mark Donohue would have (the excellent book "The Unfair Advantage" gives examples of them "bending the rules"!). Note that the head has 2.02/1.60 valves, and pushrod guides...Z28 stuff, not L48 350 stuff.

While I'm on here, I also want to recognize my good friend Bruce Hamilton from Abbottsford, BC. If it weren't for him I would probably have missed the chance to buy the Nova. Bruce steered Nancy Smith, the owner's daughter to me. Thanks Bruce!!!

Well, they actually used the 14x7 wheel from the 74 Nova SS. Easy to do.

btw, I know lots of 4-doors with posi. Back home, everyone ordered a posi so you didn't get stuck in the winter.

9C1Beater, I have a guy here in Grand Rapids who thinks that he has a 1978 2 door Police car Nova. I don't know? The car was built 12-23-77 and is red with black rally stripes. He says that the engine has a tag on it that reads SEO IB4 with a build date of 12-20-77.It is possibly a 350 4spd car. I do have the gentleman's name and phone number if needed. He said that he bought it from the original owner also. Any information I will forward on to him or have him get on here and talk to you.

Rodney has owned the car for a long time. It has all the options that the 9C1 should have but he does not have a build sheet from what I remember. Rodney will never be able to get on here as he refuses to buy a computer or a cell phone.
