[Shotimes] OT Daytona 24hrs good

[DAVID PILLSBURY]

I can answer this, Actually the Pontiac's in NASCAR use a 18 Degree Pontiac design head. Those lemans cars usually use the corporate INDY head designed by Oldsmobile. Ironically the Pontiac and Olds heads are cast in Saginaw and assembled at Buick V8 
As for the last real pontiac V8's that was the 70's but there is a Pontiac branded and built 4 banger that's cast at ProMet in Saginaw and Built in Tonawanda NY Which use to produce chevy engines. I never quite figured out why GM kept the Chevy design engine. The Olds and Pontiac's were better I thought. I know back when I was driving brand X my 454 Chevelle SS use to get slammed by a friends 455 GTO RA-4 Basically the same car same weight and options. And the GTO would beat the chevelle everytime even if we switched cars I the Shovel would lose. Then I bought a Olds 442 and that evened out that little problem. All cars were pretty much stock. Now a few years back when I had a Fiero with a 383 Chev shoved in sideways. He had a 66 Lemans with a 400 Poncho engine that I use to watch Lemans tail lights with all day long. We won't even talk about my Camaro. but I will say this a TPI Chevy is the probably one of the greatest TRUCK engines ever built. Tons of low end and nothing up top and
 a 5500 redline.

John,

My original note referrences the fact that Pontiac uses the 
Chevy Small block as their V8, what we are wondering is if 
Pontiac division uses a unique head for this sports car 
motor like they do in NASCAR (or at least they used to use a 
unique head).

It is no different from Ford and Mercury using the same 
engine, or Mercedes and Mopar now. and in race cars, we have 
Ford building a Chevy.

Probably the best indicator is who pays the bills, so yes, 
Pontiac sponsored the car, but Pontiac fans can still be 
happy that a "Pontiac" won, as much as a "chevy" fan or even 
some of the others cars where a corporate engine 
(Infinity?) was put in a tube frame custom built race car. 
And I assume that there could be some Pontiac engineering 
folks involved in research/testing in some way, and that 
benefits future street cars, if only a little.
