I have a few books at home with performance oriented casting #'s. There is a new Pontiac performance handbook (by Jim Hand maybee), that looks pretty good. I believe it has ID references. If you have specific #'s, I can check them out for you.
Not a lot of action here, I see. New to forum. I have a Barrier Blue 66 Coupe. Not a Number 1 car but pretty close. Won best GM at two NAPA shows this summer. Very fun car to own and drive.
