the "famous" CFM equation
I was playing around with the formula:
(cid x rpm)/3456 X %Ve
Anyway, I found out that 850 would be plenty, but realisticly, 750 would be ok too.
After reading Car Craft mag, the one with the 522hp 350SB, they were saying that 750 was to small for there's and 850 turn out to be right, so now I really don't know what to think! I got 50 more cubes, BIGER heads and almost the same cam...so now what? I'm back to square one!
