Rudy and everyone else of the time were doing raised port exhausts. Foder lived right down the street from Pontiac Racing's dyno facility. He got the benefit of all the work that GM was doing with the RA-V. We ended up with one of the sets of heads that CJ Batten did. Has anyone wondered why the raised port exhaust fell by the wayside? There are reasons you know.

I think Rudy was working with Straus in those days. Everyone should know by now that the 455 stroke is way too much piston speed. The only thing it really accomplishes for a race motor is to reduce the operating range of the HP curve. At least until we do a monsterous bore block. LOL
Old One, we went 146.77 with a 3450 car with this motor. What does that give you? The rumor was that Foder went up to Canada with this motor and dyoned against those Canadian boys and made almost 100HP more than them. I know Foder was packing 440 cubic inches, and the Pro Stock engines werent that much.
