Crankcase 10 10 ? Rebuild Question

[cassidyp]

My machinist says that my crankshaft has been ground to 10 10. Does this mean that I need to order undersize main bearings? I guess I prematurely ordered standard bearings on my engine rebuild kit from Pelican? Probably not the 1st overanxious engine rebuilder to do this huh? What else does this change? I would guess I need undersize bearings for the rods too? Thanks for the help

Everything you said is correct. I would clarify with your shop about which journals are undersize before ordering new parts.
