Main Bearing Clearance

There's no such thing as an oversized bearing. PERIOD. That would mean you've ADDED material to a STANDARD crankshaft. How stupid does that sound? Undersize bearings are meant to fit an undersize crankpin. Stop bein ghey.

Undersize simply refers to the inside DIAMETER of the bearing being SMALLER than a standard bearing. Dumbasses.
