I am going back together with my ls1, and wanted to know if anyone knew if there is something special I had to do to run molly rings on stock pistons. I am thinking of running perfect circle rings on my stock pistons.
thanks

well, not on this forum, but on some old skool hot rod forums say that it is the finish hone needs to be fine. 280 grit for iron rings, and 300-600 grit for chrome and moly rings. just in case anyone wants to know.
