Replace bearings after crush or put them back where they came from?
I have a 454 bbc that was put together buy a friend of mine but never cranked. To be safe I disassempled the short block to clean it since it had been sitting for a period of time uncovered. When I pulled the crank out I noticed scratches in all the bearings, a few deep enough to catch your fingernail on. The crank sat out after being disassembled and got some light surface rust on it so I took it and had the oil holes chamfered and the journals polished. The crank is well within spec for bearing tolerances, however I am unsure about using the unused bearings since the have been installed and tourqued down previously and have some light scratches, plus the crank has been polished. I realize that main bearings aren't that expensive but I don't want to throw them away if they're safe to use.
