There is a very good technical Specialist at Summit. His name is Norm and he is at extension 6652 or RKoval@SummitRacing.com. The guy is knowledgeable and helped me match my piston and rings.

GM used lots of different pistons. That number sounds like a GM casting number. Most aftermarket TRW pistons are marked "LFxxx" or something like that. You know the diameter, you also need to know how thick the rings are. I'd go with a cast or moly ring unless your bores are like new.
