Doing a basic rings, bearings on my 350 SBC. Someone in 1992 stamped their work, crank cut the usual .010 and I think (have to measure well) .030 bore. Pistons, crank, rods all in nice shape, just worn bearings, and although they look fine I'm going to replace the rings.
Clevite 77 bearings (rod and crank) are worn but stamped .010, so I can just order new .010 bearings.
Pistons are cast marking KB 120. I know it's a Keith Black piston, but I do not see any indication of 30 over or any other marks or stamps. What does the 120 indicate?
In ordering rings for just a street driver do you suggest cast iron or Moly rings.
Have not done a basic rebuild in many years, so would appreciate suggestions. Thanks.
