are his heads ported? If his heads arent ported id say the numbers are correct, plus not many 400's make 509 ft lbs, thats what the increased stroke of his engine gained him if everythng else is equal with a 400 with stock heads . Now if his heads are ported Id say he has a problem somewhere unless his cam is very small

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.
