you wont find any pontiac pistons anywhere. you can find alot of aftermarket pistons, at any engine rebuild shop, or jegs or summit or your local parts dealer. as for what you want in a piston, the sky is the limit. most mail order places dont list em, as it just takes up space, for such a small market. you have to call them.
Hey John you can google Butler performance or SD Performance they are the pontiac motor guys that have the best reputation. I have dealt with SD in British Columbia, very good people and knowledgable.
So you found yourself a Pontiac 350 instead of a 400 ? I have a complete set of 350 Pontiac OEM used rods and pistons standard bore , Too bad they're not .030" over.
