I'm going to do a 4.1 production block build. What are the part numbers/brands of hyper pistons that are 8.5:1 or 9:1 for compression, if they even make them? Or part numbers for what is actually available for off the shelf. I'd really like to go with forged pistons, but the money tree hasn't sprouted yet:biggrin:
 
Here are the old school ones..

I have a set of Venolia .030 over forged pistons. Stock replacement press fit pins with rods. P.M. me if your interested.
