Am I missing something here?? A .060 over 400 with 102cc chambered heads will not give you anywhere close to 9.5:1 CR. You're more like 8:1 if the specs you gave are correct.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
