I'm a little confused
are we talking about the connecting rod journal or the fit for the ball bearings ? big difference as what the alternatives could be, if the rod journal is out of spec then have the crank cut 010 and go with a 010 over rod if the bearing journals for the roller bearings are 002 undersize ( don't know why a shop would mess with those ) then some of the loctite 638 bearing retaining compound which is an oil resistant product can take from .005 up to .009 out of a loose fit .maybe it's just me but I've seen many things called various names ,re reading the post I guess when it says main bearings you are talking about the roller bearings out on the end of the crank !!
