Wild - Nasa wouldnt make pistons. But if they needed it, CP would probably get the job. Weisco can supply a decent competition quality piston, on the level of a J&E, venolia, or Diamond.
Ross is a decent piston but I'd call them a very good street piston. I would not call them top competition quality because of finish quality. On par with Icon or SRP which are good pistons and head and shoulders better than the Speed Pro/TRW forged deals. I don't know which ones you've used personally, but I've used everything but Venolia, althought one of my core 440s has a set in it and they look nice...lol.
