Brian, some of the guys still use TRWs and they are on the NHRA approved replacement list. Venolia, and some others have some. I know John Schloe was still using factory RAIVs in his motor when I talked to him a few years ago. I think the pin offset has to stay the same in stock, most guys use a Dykes top ring though.
Super Stock pistons are wide open though.
