Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Sorry, but I don't get it. I think you've gone to a lot of trouble to document a very, very nice LS6. But dropping the CR takes away much of what makes up the 1970 LS6. If it was me (and of course, it isn't -- it's your car and you can do what you wish, however you did solicit opinions), I'd be mixing gas. I'd ask myself how much do I really drive this thing a year. Five hundred miles? A thousand miles? How much trouble is it to buy some race fuel and mix it?

When I was looking for the EDM lifters, the Comp ones were made in China. They may not be now, but you need to check first. The only American made ones that I found were from Howards Cams.

Some guys get it and some guys don't, in the end i will be building the motor to my taste.
You have to do what makes you happy not others and i just hate having that high octane fuel sitting around my house and then bringing it with me before i fill the tank.
Car will still perform great when i am done.
I know some of you disagree with me but what can i say,in the end it is me that has to be happy with my decisions. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Donnie i am sticking to build the motor just like that &quot;quote&quot; i stated but will use the solid lifters though.
Nothing can change my mind about the flat top pistons and lower compression though, last motor i had running in there was a pain in the a@@ with the 11:25 to 1 compression, car would not run right with 94 octane and every fill up for gas i had to mix about 25$ worth of Very High Octane just to get the right gas. I really hated bringing that Cherry can in my trunk and paying $125 for each fill up.
At least with the Original LS6 rebuilt to my tastes i can drive in peace and just go to the gas station to get gas like everyone else. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] </div></div>

Danny,
Did you try playing around with the timing...My stock L78 11: 1 compression runs great on 94 octane. I would'nt think that an additional .25 compression would make that much difference.

Well you're the one who asked for opinions. I gave you mine. If you have a gas lawn mower (leaf blower, generator, chain saw, etc.) and you store fuel for it, it's just as dangerous. 87 octane is no less &quot;dangerous&quot; than 115 race fuel.

And we agree, its your car, so do whatever you want.

Have you tried Trend Performance (sister company to Diamond Pistons)?

Wayne

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Last set I got were isky. I am 10.5 to 1, solid lifter, pure stock and have run the 94 octane for 20 years, no issue. Build it so at least is goes down the track and doesn't become another cream puff with &quot;500&quot; hp.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

I put my 499 in a box, and used a Dave's Small Body HEI, which he fits into a standard aluminum distributor body. Since he has to machine the underside flat, I bought a nothing body on ebay for $5 and sent it to him. The reason I replaced my Pertroncs unit was stories of unreliability, and Dave uses components that can be replaced at regular auto parts store, if you have a problem. I think the pickup at least is actually late model Chrysler.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Why do you guys prefer the electronic ignition over the points type? I use points and never have problems. The Mallory electronic I had broke down on me.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

I did the cam and lifters in a 11.0 to 1 CR 427 in my '69 last winter.

At the recommendation of my performance shop, I went with a set of Comp Cams solid lifters with the oiling hole in the bottom. I think these are the EDM lifters everyone is referring to.

I do not remember the exact number of the Comp Cams cam, but I thinkit is the Extreme Energy series 274S.
I can check if anyone is interested.

I could not be happier with this setup.
I run Sunoco Ultra 94 without any issues.

With a M22 and 4.11's in the rear, the car will spin the tires in any gear and pulls until I run out of nerve and have to back out of the throttle.

I use the stock 499 distributor with a set of Accel performance points and a Blaster Coil.
I have not had any issues running points and the stock distributor since I bought the car in '96.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Guys thank you for all your suggestions,opinions and comments on the engine.
I will definetly run this thread by my engine builder and see what direction i will go with when the engine rebuild starts in a week or so.
I will let everyone know what parts i will go with later on in this thread.

Next is the Transmission.
I was thinking on using a Center Force Clutch package for my M22 with 11&quot; Clutch and 26 Tooth spline.
The one i took out of the car has no identification as to what company the Clutch package was but it did run well.
What are you guys running for your M22 as far as the Clutch assembly goes. I will be going with a new Clutch/Pressure plate/pilot bearing and bushing as it makes sence to have a new unit go along with a rebuilt Motor.
Here are photos of the trans etc...

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

one more photo.
Note :: The transmission has the original Muncie shifter and rods.
Yes i know it sucks but it's there and i will leave it alone.
The Hurst assembly is a much better shifter but i kind of got used to the old Muncie and it is nice to have it original. [img]<<GRAEMLIN_URL>>/smile.gif[/img]

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Hello Danny

My L-78, other then .30 over pistons, has the original compression, and I put in the crane cam, that is the same as factory spec. This would be the same came for the LS6. I love this stick. You can't beat the sound of a solid lifter cam either. After break in this spring, I put about 500 miles on the nova, and re-set them. All was good when I parked it with about 1000 miles of driving this year.
The gas I run locally is 94 octane. I prefer Mohawk gas, I`m not sure if you have them over your way. The timing is where it needs to be, and doesn`t detonate. I`m not sure what the timing is set at, sorry.
Your car, do what you feel is correct for your driving pleasure. I just want to tell you I haven`t had any issues with the compression, and solid lifter stick with local gas. Keep us posted on your final decissions.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

This is such a great post to follow. Thanks for posting all of these great pictures of the progress!! The Pertronix works like a champ. I also agree with your reasoning behind dropping the compression a tad and driving this thing. I respect the purist with all of the engine internals being at spec etc... But it’s so easy to get big HP on a bone stock appearing BB without the ultra high compression these days.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

WOW &quot;Survivor 69/Z28&quot;
i just clicked on your links in your signature,
Your LS5 Chevelle is also triple black like mine, Nice car!!!
Your Z-28 is a beauty too.

Darcy thanks for your post about the specs on your L78 Nova.

Today i did talk to my Motor Rebuilder and discussed what was said here. We are making some changes [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
We will be gunning for more compression at a tad under 11:1 we will be shopping to get pistons that will deliver about 10.5 to 10.9 compression at .30 over for the bore.
So far i will be going with the Lunati #20202 Solid cam stick (i had this cam running my other LS6 motor and it was Awesome).
The Lifters i will use is the Howards 91118 EDM Solid Lifters.
I will give more details as i go along but that is it for now as i have a lot more parts to pick and choose. My rebuilder also assured me that when he is done with the motor it will easily pull about 500 to 550 HP [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] To me that is more than enough for the street.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Today i routed my TCS vacum lines and i had to make the top pipe from scratch as it was missing for some reason.
I had plenty of pipe and hoses kicking around so i made it myself.
I think it came out rather well.
Below are photos just incase someone else has to do this for there car. It sure is a lot of small parts to hook up.
Also included photos of the other cool stuff that hooks up to the fuel lines etc...
I pre fitted everything today to make sure its all good.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Ran out of room for the photo of the NOS fuel pump.
Here it is along with other small stuff.
Does anyone know what the number is on the engine lift?
A few of my numbers are to pitted to read properly.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Nice parts/pics..those aren't LS-6 specific engine lift bkts.,as all 1970 Big Blocks used them.

Thanks Rick,
I figured out the part number for the front lift which is 3969829 [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
These would be used for all the Big Block Motors like you said.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Good detail shots! Send the bellhousing to Jerry MacNeish and having him reskin it. Shoot it half orange with a dusting of overspray onto the other half.

The 660 thermostat with #s on the base of the unit is for a pre 1968 Hi-Po Chevy. Your #s should be on the neck on the thermostat. I have a late one if you'd like to trade?

Dan

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Reskin bellhousing [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]
Never heard of that, is it a sand blast?

Thanks for the offer Dan to trade for the Thermostat housing but i will keep mine as i do not mind that the number is correct but on the wrong location.

Yesterday i sand blasted the hood hindges as they were black in color, they took me 2 hours a piece to do but the end result is fantastic.
I left them raw and just rubbed in a clear coat of tremclad rust paint with a clean cloth. Here are more photos of the rebuilt Regulator and other stuff like the Horn/Buzzard Relay,NOS Spark plugs,Starter,Battery Cables Etc...

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

&quot;Reskinning&quot; is Jerry Macneish's proprietary process of cleaning the aluminum surface and then putting something on there to seal aluminum. I have a few pieces on my Nova that Jerry did. Looks real good, can't say how well it holds up or lasts, though.

Here are the freshly re done Hood Hindges that took me 2 hours a piece to sand blast.
The raw hood hindge metal is protected by Tremclad clear rust paint that i rubbed in with a clean cloth.

Question ??
I pulled a Purple/Black wire with an end connector from the back of the cowl wiring gutter, what was the purpose of this wire?

[img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]Like the fresh weekend pass hanging on the wall from this years MCACN show [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

That purple/black wire connects to the Transmission Controlled Spark #3961573 kick down relay rivited to the gutter.
Of the 3 terminals on the gutter mounted relay,it fits to the passenger side terminal,nearest the firewall.
The wire should have a female end to slide onto the male spade.

Thanks Rick,
so it would go like this correct?
I wonder why the last owner did not have it connected?
Also photo shows the pedal wires, is everything correct down there?

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Rick i just took my Wire gutter off to have a closer look underneath.
I do not have a fourth connection like that smaller photo you included, maybe the connector broke off? Does not have any signs of being broken off.
Maybe the four speed cars were a different unit than an automatic one. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

The third spade is broken off. It would be in the upper right corner of your picture and would be on the opposite end of the metal strip that is riveted to the bakelite.

Because of this you cannot connect it correctly. The black/pink wire should go to that missing terminal end. Where you have it now is actually a locating tab that the two prong connector mounts up against. However, it will still function correctly where you have it.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

Thanks Rick,
Now i know why the last owner tucked that wire away in the Wire gutter.
I'll have to live with the Broken one for now until i find a good used one still rivited to the original wire gutter.
At least it will work hooked up like i showed in my photo as i see it runs to the same connection. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Hey Danny
Nice Job on the details, this post is very helpfull for me as i am restoring my chevelle.
The Photo you have of the Wiper Motor helped me finish wrapping the repro wires to factory specs.
Keep up the good post.
Do you have any photos of the Radiator, i would like to see what that looks like.
Thanks.

Thanks, i see you are new to the SCR welcome.
Sure i can post my Radiator for you, also will include the NOS Water pump. Original Radiator was rebuilt by the last owner just before i bought the car. He added an &quot;IF&quot; side tank to go to a 4 core but i also recieved the &quot;IA&quot; side tank with the car. If you look closely there was a repair done Just over the &quot;H&quot; were the &quot;Harrison&quot; Logo is.
Last Motor ran super cool with a 160 degree thermostat and the 4 core system. I will re-install it the way it is set up now. The LS6 is an original 3:31 Geared car so it does not have the tab on the top Rad cover but the bottom does have the extension tab on the drivers side rad cradle frame.

You are most welcome, I have a bit of experience with the these things. I did notice that you do not have the typical washer behind the like the Novas have.

Greg

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

That is a great thread you have there Greg.
I see what you mean, the Nova always had the washer behind the rivets and on my chevelle there is no washer behind the rivets.
Maybe other guys here can check and see if there Atlanta built chevelle is done in the same fashion as mine. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

I have a tip for a sagging Wire Gutter unit, i used a heat gun to heat up the plastic and after it softened up a bit i put a weight (Like a heavy flat Book) to sit over the whole unit for awhile.
It is nice and tight again without the plastic sagging down with a large opening on the top keeping the wires in place a lot better.

Re: 1970 Chevelle SS 454 LS6 Rebuild + Details
 

I have one of those 3961573 parts that is still riveted to a gutter, but I can't tell if the gutter is the same as yours. If you can post a good shot, I will compare them.
