",,,It seem you do not understand how increasing bore and stroke the legal amounts (engines ci's) while holding the other specs constant will increase CR to be higher than the stock engines CR..."
Stan, I ain't the sharpest knife in the drawer.
BUT I did finish high school & 3 years of college. Made pretty good grades in math, up to, but not including trig.
I DO understand that if you increase the size of the hole and/or the length of the stroke, the cubes & compression will increase. Volume of valve reliefs, deck height, gasket thickness/hole size, piston to cyl wall clearance, & distance to the top of the top ring are also involved in figuring true compression.
BUT, the MAIN thing I'M talkin about is the SMALL size of the min chamber size allowed, which is much smaller than any figure I've ever heard of, or read about, that Pontiac ever advertised, or that any Pontiac guy has ever actually measured. MAYBE somebody at GM did actually provide NHRA with the small chamber sizes, & NHRA just took their word for it & didn't even check. I DON"T KNOW !
Hey, I'm not suggesting that I think NHRA should do anything that will make ANY Pontiac engine less competitive.
As far as I'm concerned, I'd like for every Pontiac V8 to have NHRA numbers that would make it competitive, in whatever class it runs.
So, what's your problem ? You & me seem to get crosswise here & on the PY forum. My suggestion is that we avoid each other as much as possible. You agree ?
