WTB Pistons
I’m looking for pistons to go with my 4.5 crank and 6.8 rods. Prefer Ross with a big dish. Aftermarket block hasn’t been bored yet. New or lightly used. Thanks.

I have a set new 4.250 bore 990 pin 35cc dish made by Ross. The piston sheet says 1.290 compression height.

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.
