I use this calculator, it accounts for ring back volume, gasket volume, etc.
http://www.diamondracing.net/tools/ When I put in a 6.7cc piston dish and a Felpro 1016 gasket,0 deck, 92cc chambers, I get 9.7 CR. Maybe a little less if pistons are .005" in hole. (hard to see without deck bridge) Use a cam with at least 230* intake duration and 112-114LSA.

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.
