piston ring choice. sbc

Post by turbotater »

Is there a piston ring set available for a mild turbocharged sbc 355 in 5/64 that is less than hellfires and you don't have worry about moly flaking off if there is mild detonation?

I have always used Molly rings on all my forced induction engines with zero problems.

5/64 rings sounds like some old stuff or non forced inductions pistons.

This is using some old 2256 pistons and I am just a little concerned that the owner of the car may run into a situation of bad gas and heavy foot. I had the engine together for a while on some cast pistons and plain rings and I had no failure but while it is apart this time I was thinking about a small upgrade.

Mild turbo should be OK on moly. Just open the gaps according to the boost level.
