What's the Best Moly Piston Rings on the Market:
Perfect Circle,Sealed Power etc. for a sreet engine? What's the deal on "Barrel Shaped"? Need to order a set real soon.
I'm running Sealed Power single moly set in my .060" over 350 and they've
sealed up really nicely.
Barrel shaped just referrs to the face of the ring (the part that contacts the
cylinder wall) and just means it is slightly convex, as opposed to tapered
or angled from top to bottom, for instance.
