The most "significant" Chevrolet performance car?
Sounds like a rhetorical qustions...everyone knows it was the 1967 Camaro RS/SS 396 4spd Indianapolis 500 Pacecar!!! https://www.yenko.net/ubbthreads/imag...ns/burnout.gif https://www.yenko.net/ubbthreads/imag...ins/3gears.gif

Re: The most "significant" Chevrolet performance c
 

significant car or shall i say cars would be any 55 Chevy with a V-8. had that V-8 not been introduced in 55, none of the others would have been where they are today

Re: The most "significant" Chevrolet performance c
 

significant:

4. having great power or influence

https://www.yenko.net/ubbthreads/imag...mlins/flag.gif As far as a model of car it would be hard to argue the "significance" of the 65 Chevelle Z16. That is what turned street muscle into a big block frenzy.
https://www.yenko.net/ubbthreads/imag...mlins/flag.gif A particular example of this car would be the prototype which is right here on this site with Dave M.

Re: The most "significant" Chevrolet performance c
 

I will put my vote in for the original grand sport corvettes.

Re: The most "significant" Chevrolet performance c
 

My vote is for the L88/ZL1 Corvettes. One RPO number assured you of a complete factory-built race car, an entire PACKAGE of mandatory components and unavailable items designed for and tested on the proving grounds of the world’s greatest racing circuits, Le Mans, Sebring, and Daytona.

L88/ZL1 Corvette… not simply Chevrolet’s pinnacled race gas-only fueled 560HP+ engine sitting in America’s great sports car; a top-of-the-line racing machine.

No other car mentioned in this poll could outperform these giants… in speed, handling, braking… PERFORMANCE and made available to the buying public.

That’s SIGNIFICANT.

Re: The most "significant" Chevrolet performance c
 

Heres a question to go along with this thread........are we talking car or motor or both? I think it would be extremely hard to pick just one car, with the Blue Flame engine, first V-8, Bel Airs, lightweights, Grand Sports, COPO, ZL-1, etc..if you think about it, all of the cars everyone has mentioned is in a class by themselves, hard to compare and contrast.

Re: The most "significant" Chevrolet performance c
 

63 GS Vette with the Aluminum motor and side draft webbers... IMHO "The Holy Grail"

Re: The most "significant" Chevrolet performance c
 

How come nobody has mentioned the father of muscle cars, the GTO!. Sure it's a pontiac but still a GM product. I would have to say the Corvette. With all it's incantations through the years and continuing to be a leading contender in the performance world gives it the #1 spot for me. As far as the most significant corvette?, depends who you ask, for me being a musclehead i would say the 69 Zl1, ask a racer, collector, geezer, you'll get different answers. For contributions to GM credit the vette far exceeds any other model. THE BLUE DEVIL!!!, nuff said.

Re: The most "significant" Chevrolet performance c
 

One of the cars that "got me" in the sense that Rob describes it was the first time I ever saw the 68 Dick Harrel Chevelle in Muscle Car Review when Joe Sweezy owned it. I must have read that article over and over. This was before I ever came to this board, so my thought was I would NEVER be able to ever own a supercar of any kind! https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

Re: The most "significant" Chevrolet performance c
 

I agree that the most "significant" Chevrolet is likely more a personal thing than something to be agreed on by the masses. Grand Sport vettes mean nothing to me personally, nor do any Z11 Impalas or convertible Z/28s, not to say they weren't important cars for Chevrolet, and to others, but none of those were significant in ME becoming interested in what I'm into today. I'd say the car that sticks in my head as "the one that started it all" was when Brian Henderson brought his freshly restored fathom green 69 sYc Camaro to a little local show in my hometown on his way to the Camaro Nationals some time in the early 90's. I know I wasn't old enough to drive, and my brother Erik was 5 years younger than i was...so we were both pretty young...Regardless, we knew what a Yenko was from the many stories my dad had told us over the years... and ironically were probably about the only people at that show who did! I talked Brian's ear off for an hour or more about the car, and he answered all my questions and mentioned he thought it was cool that a couple of punk kids showed that much interest in learning about Yenko specifics. It was the coolest car I had ever seen, and at the time there wasn't anyone else restoring Camaros to that level of detail. (probably still isn't as far as that goes!) It was the first Yenko I ever recall seeing "in person", and to this day it sticks in my mind as one of my favorite supercars ever.

That day started a friendship with Brian that has spanned close to 20 years now (wow!) and that Camaro is what got my blood flowing and eventually lead me to where I am today. On a personal level, I'd definitely say that green car was the most "significant" one for me...

Re: The most "significant" Chevrolet performance c
 

I'd have to say that everyone has had great choices. Frank's original question was "What do you feel is the most significant single CHEVROLET performance car in existence?"
No offense to Frank, but the word "significant" has too many broad meanings to all of us to really agree on just ONE. Some have interpreted it as the most significant one for "them" personally which got them into the hobby with such focus, others have picked the highest horsepower, or the very first OHV V8. My pick hinged on Chevrolet's most complete racing package ever offered under one RPO. (and by the way, I stand by that; the L-88s nor the Z-06 Corvettes, nor the ZL-1s were offered with an overall package of race-only features as was the Z-11).
Does that mean the Z-11 was the most "significant"? No. It just fit the criteria I used to answer the question, as each of the other cars mentioned fit the criteria of the people who mentioned their picks. https://www.yenko.net/ubbthreads/imag...iggthumpup.gif

Re: The most "significant" Chevrolet performance c
 

I've got to agree with Joe - sometimes the most "significant" Chevrolet performance car to some can be an uninteresting car to me. Don't get me wrong, I love cars and can appreciate the hard work and devotion that can go into any car, be it a muscle car or the most bizarre creation.
When I was 15 there was a '59 Studebaker Lark post car for sale in a gas station in Hempstead. It didn't matter it was a 2 bus ride to get there - I was there twice a week, to look, until it was gone. He wanted $600 for it, if I could have gotten my Dad to loan me $550, it would have been mine.
The hood and front fenders were molded together and tilted forward. It was bright green metalflake with a 327 - 4 speed and straight axle front end. The inside was an entire black '64 Impala SS interior, buckets, console, door panels and dash. I was in love, hooked on that look, straight axle, custom interior and big motor!
Loving the look wasn't enough, it wasn't a Chevy - This lead me to a long line of '55 Chevy's and my most "significant" Chevrolet - not a factory produced car - but a Two Lane Blacktop style, big block, 4 speed '55 Chevy. We were building them years before the movie came out! Nothing has the look, the feel or brutal power of a car built to those standards. To underestimate the effect of these home built hot rods on GM's future decisions would be an injustice!

Re: The most "significant" Chevrolet performance c
 

Verne,

I agree with you that “significance” is a somewhat subjective term and would not try to argue any one choice is “correct” but I believe we may have a difference of opinion with your statement that the RPO-Z11 was the most complete racing package ever offered by Chevrolet.

Let me reiterate: RPO-L88 was a COMPLETE RACING PACKAGE; not an engine-only option. This applies to the RPO-L88/ZL1 Corvette only (not the ZL1 Camaro which we agree was NOT a complete packaged race car).

The Z11 was of course one of the most SIGNIFICANT race cars in its time but I don’t believe it can be said it was a MORE complete package. Wanna compare lists?

Regardless, two incredible factory-built race cars. I give the L88/ZL1 Corvette the nod as being more significant because it could be ordered by anyone with the money and patience.

Re: The most "significant" Chevrolet performance c
 

I don't mind a healthy debate. Make a list of all the features that were unique to an L-88 Vette other than those which were standard on any other big block Vette, and I'll do the same for the Z-11 Impala. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

hello,
i dont mean to steal or change the direction of this thread.but i'm the guy who built the blue z/28 convertible.
a friend informed me of my car appearing on this site and i have read the posts.

i would like to clear some things......
i have no wrong intentions on the build of this car.yes the engine has been properly broached,stamped etc....i have been very open on this build from the very beginning....

why i did it was because it can be done....we all know this practice is going on...i'm not hiding behind a clone but rather standing in front of one...

if it ever shows up at an aution for $800k as previously mentioned the new buyer will sign a legal document that he or she is knowingly purchasing a recreation.and i will always retain that document.

Re: The most "significant" Chevrolet performance c
 

Interesting that you consider the L-88 a package. It was not bundled as such. When ordering the L-88 option, there were of course some mandated options but they were priced individually.
The ZR2 package, available to the '71 LS-6 engine was a package. The list price was $1749.00 and included the MA6, K66, V01, J56, F41 etc, along with restriction of options that couldn't be ordered, just like on the L-88. However the above options were NOT available separately on other models, which is not the case with the L-88 years. Those options were available separately and could have been ordered with other engine options.
So as to a "racing package" you would need to give the nod to the LS-6 ZR2 Corvette of 1971.

Re: The most "significant" Chevrolet performance c
 

I'm a little confused by the list of RPOs such as K66, J56, F41, etc that were bundled with the ZR2 package, but were not available on other Vettes. Why were they RPOs then, rather than just additional "special equipment"? https://www.yenko.net/ubbthreads/imag...s/confused.gif

In any case, here is my list:

RPO Z-11 Impala features

* The 427cid engine itself: special crank, rods, pistons, heads, cast push rod guides, intake, valvecovers, water pump, air cleaner, oil pan, balancer, flywheel, hollow fuel pump rod, fuel lines and filter, plus misc. fittings, brackets & springs
* Special suspension, including Corvette Z-06 brake backing plates with unique metallic linings, unique coil springs & ball joints
* Special roller type rear axle bearings, retainers and studs
* No body sound deadener
* Cowl induction
* 15x5.5” wheels
* 4.11 positraction rear axle
* Aluminum body components, including hood, hood lock support, front fenders, front and rear bumpers & brackets, front splash shield, grille brackets, fan shroud, battery tray
* No other options available
* Only 50 of them were built just to satisfy NHRA’s requirement for Super Stock.

None of the above was standard equipment with any other 409 car. And the only items above that were optional on other models are the 15x5.5 wheels and the 4.11 posi.

Re: The most "significant" Chevrolet performance c
 

I have no dog in this hunt, so I am going to let go on what I think.

Personally, you have to look at what started everything before anything else can develop. You have to include some cars not mentioned such as the original Corvette. True, this was not a barn burner, but it was a platform that could be built upon. The '55 shoebox with the smallblock. It was the everyday car that put the chev smallbolock on the map. The 409 Impala, a big car with grace and speed. The Z16 chevelle, the '67 Z/28, the ZL-1 camero, and the LS-6 Chevelle and Corvette. All of these cars are without a doubt very important cars. Dealer cars are a a different bag of chips.

For me, the most 'significant' Chevy is the one in someones garage that they would rather part with their first born than that car. If it was not for the passion that is ignited within on these cars, then Chevy, Ford, Mopar would not have developed the car for the 'enthusiast'. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

Re: The most "significant" Chevrolet performance c
 

Verne,

During the 1968 and 1969 Corvette model years those RPO items were available as separate ordered options on L-36, L-68 & L71 as well.

However in 1971 those were what made up the ZR2 package and are listed on the Corvette Order Copy sheets as ECL codes. They weren't even listed on any ordering form as separate items or referred to as RPO items. They were however spelled out in GM's verbage as to what the ZR2 package consisted of.

Re: The most "significant" Chevrolet performance c
 

Verne,

As I said previously, I challenge, with respect your statement that, “(No) L88s… were offered with an overall package of race-only features as was the Z-11” and that, “there was never another Chevrolet produced with so many specific packaged features for one purpose”.

Well, before we compare packages to see whose is bigger https://www.yenko.net/ubbthreads/imag...mlins/wink.gif let me add the disclaimer that I do not profess to be the definitive expert on this subject. For many reasons I will attempt to explain, the subject of the L88 PACKAGE remains convoluted and open to much misconception. Hopefully my longtime interest and consideration of the matter will prevent me from adding to the confusion.

To begin with there has always been a cloud of mystery over the entire L88 program, starting from the upper echelons of General Motors themselves. This was a tricky proposition for GM; forced to make a bona fide racer available for particular eligibility requirements in the professional racing circuits. Made technically available but not marketed aggressively; in reality, heavily discouraged. A result of this is very little of a paper trail showing clearly what the L88 was all about.

But let me assure you, the L88/ZL1 Corvette was top-to-bottom, front-to-back all-out RACE CAR. The car delivered to the county’s top race teams was the very same “packaged” version available to all.

Did the package have a name? Well, not officially during the time of its production. That wouldn’t happen until ZR1/ZR2 package was released. But it was essentially this SAME package, without the L88’s special induction hood and the full race 427; these goodies were specific to the L88 alone. By the way, when I use the term L88 it also INCLUDES the ZL1. Every ZL1 Corvette is an L88 as well; the L88 order ensured you of the accompanying racing package, the ZL1 is the aluminum engine case only. If you’ve ever seen ZL1 documentation (tank sheet, etc.) this point is clear.

The package was ordered not by a designation code but by simply ordering the RPO-L88 itself. You could walk into a parts department and buy the engine alone but you could not have the factory install it on any other car but the RPO-L88. Ordering RPO-L88 meant that you were required to take a full list of other RPOs and special items. The choice was not yours; Chevrolet would not sell you anything other than the full-race configuration car. It also meant there was a list of things that couldn’t be ordered. Check the box for a radio and your order would be discarded, literally. Want a fan shroud to help keep the engine temperature tolerable? Forget it, the car was meant for the track and the track only. If money was no object and you thought power steering would be nice… dream on; this beast was anything but nice. One basic version, few allowable variances… take it or leave it. And you might not get it even if you towed the line. It was rarely easy; it required patience and persistence.

In evaluating the “completeness” of the package I give little weight to whether or not the individual elements are made available elsewhere. It is not contingent on how exclusive the individual components are. Nor do I give credence to the fact that how it is broken down for clarity or pricing purposes dictates its completeness (let alone its actuality). Tallying individual specifics, especially on different models from different time periods runs the risk of the apples and oranges analogy.

You tell me the Z11 substituted many aluminum body parts for the Impala’s metal parts; I counter that the Corvette is an all-fiberglass –bodied car, designed specifically for its lightweight characteristics. Tell me that the Z11 came with wheels that were .5” wider than what was available on a standard Impala, a positive attribute for adding a bigger racing tire, granted. I counter that the L88 Corvette came with an even wider rim; no points should be lost because other Corvettes could be had with these wheels. The point is that the equipment that was supplied with EVERY L88 order was what Chevrolet thought was necessary for racing (and racing only).

It was the technical developments of the L88 program that dictated the overall refinements of America’ only sports car. The purpose of Corvette engineering was to reach the highest level of both style and performance. The Corvette wasn’t plucked from the economy level of the Chevrolet lineup and modified for occasional forays into off-road endeavors. The Vette was all about performance… going fast, taking corners and quickly stopping. So an argument can be made that every mechanical change the Corvette underwent was in order to upgrade its overall performance, even as far as its body style design. The styling change from the midyear cars to the C3s was as much for aerodynamic purposes as it was for aesthetic appeal. Talk about development with performance in mind!

Example: since the advent of fuel injection in 1957 every high performance engine in the Chevrolet lineup with the exception of the “W” 409 was for the most part a result of Corvette-based technologies; the top power-plants that wound up in the Impala/Chevelle/Camaro/Nova engine compartments were generally supplanted Corvette motors.

You would be hard-pressed to contend that the Z11 was in any way the pinnacle performance achievement of Chevrolet history. I wouldn’t make that claim about L88/ZL1. Time doesn’t stand still; it never has. Modern innovations, especially in the Corvette arena obviously surpass those from 40 years ago; the latest model Corvette or Camaro is just as eligible as someone’s choice as most significant and in that regard there’s merit in the claim that a new Z06 is inherently an all-around better performing car than anything from the ‘60s. Improvements have not always been linear with time; there have been peaks and valleys. One of those peaks for Chevrolet was 1969-1970. We all know the story: factors of environmental concerns, oil supplies, safety and insurance issues, etc. saw the sudden end of the “performance years” and a steady decline in horsepower ratings. True performance has since returned!

The Z11 is for me one of the hallmarks of Chevrolet performance history; definitely something on my “wish list” too. On a personal level, no car is more significant to me than my 1960 Chev Biscayne drag car, mine since I was too young to drive. I’d hardly expect it to receive another vote in this poll; that’s why I chose to instead cast a ballot for what I consider to be the most significant “performer” of the muscle years. L88/ZL1 Corvette was the apex of Chevrolet performance (made available to the public) during this time and for many years following.

I have been in discussion with the top levels of the NCRS, the Corvette Museum and General Motors about finally lifting this veil of mystery with respect to the package aspect of the L88. The NCRS judging manuals acknowledge this package aspect as do all leading experts in the L88 field. Much more needs to be done to get the word out to the general public, IMHO.

So Verne, I’m quite confident you will be able to see the L88/ZL1 Corvette was the whole package; this was the car that was culmination of Chevrolet’s racing involvement and evolvement. Nothing was held back; why would it have been? Each L88 was complete and race-ready as delivered from the factory; simply bolt on the available race exhaust system and your tires of choice and you’re ready to go, and go fast. The L88s were world-beaters, capable of speeds as high as 200MPH with the right axle ratio. And durable… you don’t win the 24 Hour Endurance Race at Le Mans or 12 Hours at Sebring in anything other than the epitome of performance excellence.

Conclusion: the RPO-Z11 and RPO-L88/ZL1… both FULL RACE-ENGINED and race packaged cars. Both extremely significant!

And with that said, here is the listing of the (’68-’69) L88 RACE PACKAGE:

MANDATORILY REQUIRED OR UNAVAILABLE OPTIONS/ITEMS:

(*) L88 only
• L88 Special 427 “blueprinted” engine (FULL RACE) *

Great post! I will admit, i never knew too much about L88 Corvettes but after reading all that i feel like an expert. https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

Re: The most "significant" Chevrolet performance c
 

Your not correct on the dual plate clutch. The L-88 used a special 12.5 inch light weight flywheel and single 11 inch clutch disc.

Re: The most "significant" Chevrolet performance c
 

Rat,

My sources indicate that every 2nd design L88 and ZL1 Corvette came with the dual plate clutch. The information I was passing along was slightly condensed to give some general facts; not all info is entirely accurate for every incarnation of the car in its 3 year run.

As I said, I'm NOT the definitive authority; I just thought the package aspect was worth sharing.

https://www.yenko.net/ubbthreads/imag...lins/beers.gif

Re: The most "significant" Chevrolet performance c
 

I'd say the L-88 is more fun to cruise at 150 mph. A set of 3.08s help of course.

Re: The most "significant" Chevrolet performance c
 

L88vetteron,

The L-88/ZL-1's used a special clutch assembly with these part #'s flywheel 3866735, pressure plate assy 3886066 & clutch disc 3886059. Which is a single plate 10.4 inch, not the 11 inch I stated incorrectly above.

The MA-6 HD dual plate clutch design used two different set-ups one for 427 usage with L-71/L89 and one for 454 usage. '69 application was flywheel 3955151, pressure plate assy 3959175 & clutch discs 3959176.
'71 454 application was flywheel 3992094, pressure plate assy 3993814 & clutch discs 3993815.
There also was a special pressure plate for these dual plate clutches 3955148, this was a unique floater plate used with both dual plate clutch applications, 427 & 454. The flywheel differences are due to 427's being internally balanced and 454's being externally balanced.
