OK, here is what I got.
455 block. 4.22 bore, 4.25 crank (comes out to 475.55, not 474) 475 cid, ol E very basic wide ports wide ports 7.71 best ever, usually 7.80 That is very good, impressive. But the block on borrowed time. Aftermarket block, 4.35 bore, 4.5 crank and new ported CV-1s and required intake, 7.61 Closest is a tenth difference but usually two tenths difference. Is that about right or is there some other factors missing ? |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
