What do you mean by saying that the intake somewhat matches the heads?
I could deal with the interface at the flange being somewhat smaller since that is a straight run and it does not even take the area of a wide port to flow 370 cfm, but you for sure need a good amount of added port area from the point in the manifold where the runners turn hard and from that point on up to the intersect of the runner and plenum. I going to go with a what I think is a generous 770 hp , especially in light of only having 11 to 1 compression.

There is power to be had by deliberately mismatching the intake runners at the gasket flange on certain combinations.

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.
