I am freshening my 400 stroker and need new rings. Is there an advantage or disadvantage in using a low tension oil ring? I don't use nitrous. Thinking of a plasma moly faced ductile iron top ring, reverse twist second (iron) and standard tension oil ring. So many makers. I'm using Ross pistons. Recommendations?

Don't use low tension oil rings n a street motor, unless your running a vacume pump on the crankcase I don't use the low tension oil rings on my race motors without a vacume pump either

Whats the application? Intended use? You can defiantly tell a diff turning the same engine over by hand using low tension oil rings, then same engine with standard oil rings.
So theoretically there is some power to be gain by friction loss.
I run a vacuum pump with low tension oil rings to help control the ring seal.
If this is not a all out effort type engine deal forget the low tension oil rings.

I saw some rated at 18 pounds(low tension) and some at 23 for standard tension, so Ill just go with standard. I don't have a pump, don't use nitrous, don't drive it on the street. Compression is 12to1
