I am no expert but Do not go with a 4.5" stroke and lightweight pins are also a big no no. U need thick wall pins. I went with a 4.25" stroke and was pretty happy with the power it made. I feel that the block will survive with the splayed caps and 3.25" main will make the crank strong vs 3" at the cost of rpm capability which does not apply with your 6000 rpm red line. Good luck.

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.
