standard size rings in a .020 motor?

Lyn,
I've seen that happen before. I would say your assumption is correct.
The worst case I've seen is when a guy came in with a 350 he rebuilt and complained of a knock. The engine bore & crank was Std., all except one
.009 rod journal that GM had put on the crank. Then there was the guy that had me build a complete (when I say complete, It was complete from flexplate to water pump) 350 to exchange for his knocking 305. When I got around to taking his core/exchange engine apart I hit the first bolt on the flexplate with the air impact and the flexplate fell of the back of the crank. I had picked the only bolt that was holding a cracked flexplate on the crank. Upon complete disassembly the core engine was found to be O.K. It went back in service as a Std./Std.Std rebuild. What can you find that John Q. Public does??...Go figure!!
