Thanks!
I think I’m going to stick with cast rings, I think moly rings need a perfectly squar cylinder and are harder to seat. I have a few bore that are 1/w thou difference here and there. I’m lucky as there is Zero ridge on the block!
First off, I've never seen an engine with any kind of run time not have a ridge. May be small, but it's there. As to cast vs moly, the only thing I would put cast in is a lawnmower. I've re-rung engines with up to 0.009" taper with moly and had no problems. But this is just my
, it's not my engine.
