I figured it was sitting there(the short block) so what the heck! and a 400 will hit softer with a stick than a 428 or 455! And I have a 33 spline 12 bolt ready also.
I think Tom S has a 557 block dyno mule that has seen 500 HP+

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.
