Pro Stock Pontiacs
I was looking at the Nostalgia Pro Stock Association groups cars and it got me wondering about how many Pontiac powered Pro Stock Pontiac cars there were back in the day. A few come to mind but I'm sure that this group can come up with some more names and pictures. Bert Straus's Astre, Rudy Diephuis's Astre, and Jerry Steinbeck (sp) Grand Prix race car are the only ones I know of.

At that point in time were the Pontiac powered pro stocks using stock blocks and even stock heads?

Real Pontiac blocks and heads.
I think they could be ported etc. Not sure if they could be welded or cut though.

My understanding was that Bert Straus' heads had the intake ports welded. Looking at the engine back then, it was clear he cut off some of the exhaust port and made a new higher exhaust port.

Interesting read. Jerry Steinbrick's Ram Air V Pro Stock car is listed. Also Animal Jim's Mamouth Mercury which we raced with the Beswick Grocery Getter Tribute car. (3-0), against the 735 Cubic Inch Monster Nitrous Mercury.

I'll bet some of the really short wheelbase subcompact Pro Stockers in the day were a handful to drive!

I saw a Nostalgia Pro Stock early 70's Firebird on the Nostalgia Pro Stock web site that has Boss Bird on it. Did Arnie Beswick ever actually build and campaign a Pro Stock car?

I wonder how many stock blocks the pro stock Pontiacs split in half. Was pro stock a 500 inch limit back then? If so the Pontiacs must have been a 4.5” stroke to get the cubes out of the limited bore size in the stoke block configuration…. ya think?

The 500 cubes limit on prostock started around 1981. Everything was based on weight per cid before that.

I will dig out the super stock build up guide I still have from HO racing .
I can't recall exactly the year ( 74 or 76) but at that time the only porting allowed to be done on the heads was no limited to no more then 1 inch deep from the flange face. So that amounts to nothing more then a gasket match.
