Yes, measure the journals on the crankshaft. I bought a 72 motor and it was.020/.020 from the factory. Crank will be marked if it was under from the factory, but offhand I don’t remember the markings. My book at home will tell what they are. Bearings go to .03 under unless you by china bearings. I have seen them.060 under, but at that size you risk grinding off the hardened part of the journal.
