I have a Melling cam that is the same grind as the Summit 2801 and a stock GM HEI distributor. I think I am running 12 degrees of initial timing and get no spark knock with this 400. Your compression may be more than mine.

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.
