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)?

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.

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.

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.

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.
