Napster- I have the Exact same engine specs as yours, my CR is 9.8, same exact cam, I idle at 700 with mine but it’s a 5 speed in a light 87 Formula, it revs very fast. I had my 47 heads done by Steve25 to flow 250 and the car is scary fast, and will break tires loose on command. all the cam the motor needs IMHO. I have built 461 before and this is my 2nd 434, I prefer the 4” stroke.

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.
