Main Bearings .001 over or not?
So working on a motor right now and need to determine if I should order standard main bearing or get a set that is .001 over. The Tolerances for the crank mains are 2.7484 to 2.7492. Each main has been polished and measures out at the following:
2.7485, 2.7484, 2.7484, 2.7483, 2.7483.... So All of them are on the bottom end of the spec. the machine shop said that if I was on the bottom end to order a set of .001 bearings, but in my research I have found conflicting info. I know that no matter what we will need to plastic gauge and confirm oil clearances, but would rather not order 2 different sets of main bearings if I can order it right the first time.
