Steve B. used a 1959 389 block to get to 577 cubes; deck raised two inches.
*Novel six bolt main girdle and best of all, topped with M/T hemi heads.

Posted this afternoon.
Stan Digitizing Cylinder Heads Help http://classracer.com/classforum/showthread.php?t=73754 Our people say they can get to 99% accuracy from a port, however, when going to the seat area, there are metrics like "picking the throat size." In this case we chose to go 92% that reduced flow quite significantly, so be very careful. We are doing a 642 cubic inch Pontiac engine and the throat size is the limiting factor. We brought the flow back with a carefully constructed intake manifold runner by Mr RPM himself, "the Kat" Rick Katterjohn. Lynn McCarty www.ramairv.com 317.260.3486

If your ultimate goal is power and your not restricted by rules then it's far and away cheaper with less headaches to pump a good amount of boost into a smaller motor.

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.
