340 bore tolerance question
:salute: Hi, I have end fitted my compression rings in a used 340 block .30 over. I have 3 cyclinders with a .003 bore taper from top to bottom. The ring end gaps were running from .017 to a max of .023 on a couple, but never more than .003 differance in any one cyclinder. My one book states .010 to .020 is acceptable on a small block, the same book states .013 to .023 is acceptable on the 340. My question is, do you guys think .003 bottom to top is excessive bottling? The pistons are flat tops that stuck out of the deck when I tore it down. thanks "your mopar brother Walt" :sad:
