OK. Does anyone know of a company that makes stock forged pistons for the lm7 motor? I saw Wiesco's site. But those pistons raise the compression. I'm running a turbo. I would like to stay low on the compression, if not lower.

I don't know if they make forged 5.3's you might check the truck forums.

I bored out my 5.3 block & used 5.7 pistons.
