This suggestion is similar to a example of a 455 that made 410 hp @ 5500 rpm and 512 ft.lbs. Tq @ 3600 rpm:
Bore it .030-over, use a Performer intake and a 750cfm carb of your choice with a good quality set of 1-3/4" 4-tube headers. You didn't mention your heads. one example, 6X reworked to to 200-210 cfm (28") at .450 lift. Then establish exhaust flow of 70-74 percent of intake. This will pair very nicely to a Comp Magnum 280H hydrulic cam. And I would also suggest aftermarket steel rods and good quality set forged pistons.

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.
