Re: Need Pistions You wont really find em off the shelf in a stock size (3.90) but plenty of sponsors have em ready to go if you hone the block out (3.905) to clean up the cylinder walls.

Re: Need Pistions You could get them custom made, but they will be expensive. Why do they have to be stock bore? If you're trying to save money, the difference between custom stock bore pistons and off the shelf 3.905's will pay for the honing at the machine shop.
I got Lunati flat top (NHRA stock class piston) but they don't have valve reliefs, and I still ended up having to hone .003 to get wall clearance. If I were doing it over, I'ld get JE's and hone .005!!
