you should be able to get it into the 9.25 to 1 range fairly easily with flat top pistons, zero decking and milling the heads about .030 -.040. I am working on my '72 455HO motor and when I measured the heads (which appear untouched), they actually measured closer to 106-108cc's so with a little milling they will be in the 100cc range.

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.
