I need to order some pump gas pistons for my KB wedge 572 C.I. (4.500x4.500) B1 build, I'm debating between Diamond, Ross or maybe CP. I'm not trying to make an all out drag race or any type of race motor so the trick of the day is not needed.
I'm thinking 1/16,1/16, 3/16 ring sizes with standard tension oil rings and maybe a better 2nd ring like a Napier design.
Who do you B1 guys like for this type of piston?
All help appreciated
