Long story shortened: Small block Chevy (355 C.I.). ATI procharger P1SC. Keith Black forged pistons. Speed-Pro Ductile Iron Moly Rings. Car is a street driven (someday if I ever get it finished) '66 Corvette which will probably only see short bursts of full throttle ( I am a truck driver so I don't need to lose my licence).
Speed-Pro suggests a ring end gap of .024-.026...(.006" per inch of bore)
Keith Black suggests .020 ...(.005" per inch of bore)
Right now I am at .021" on all 8 cylinders ( good machinist?)... Just wondering if I should file them out a bit.
I would imagine that Speed -Pro would rather you gap them large so the ends don't butt so they don't get blamed for any damage.
On the other hand , the tech guy at KB Silvolite seems very knowledgeable and probably knows the characteristics of their pistons.
