I have sent cranks back to have them made another .0010 smaller, lots of general, not race machine shops, automotive machine shops like tighter bearing and piston to wall clearances down twocents
More oil flow means more bearing cooling to me up work
I've never spun any automotive engine bearings from being too loose (Correction, sorry), I have seen spun cam bearings as well as rod and mains spin from bearing to crankshaft contact from being to tight whiney: puke down work
