I built my own using parts from Paul in Fl. Www.5speeds.com
I have a pretty strong 428 and went with an iron case and billet mid plate. You’ll probably want to do the same with your Cubic Inch. I went with a 2.64:1 first gear. 2.43 is also good. I would stay with those 2 ratios for strength. Sent from my iPhone using Tapatalk

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.
