Bering tolerance question
Doing my first engine rebuild. Rb25det. Had the block bored and when I went to put the crankshaft in I used plastigauge to check the bearing tolerance. I’m a bit under .051mm for the rods and right at about .051mm for the crank. The book says I should be between .020 and .040 for the rods and .028 and .046 for the crank. I assumed I would need to buy oversized bearings but when I started reading online some people recommend having more tolerance on a build when you are trying to push higher horsepower.
Just wanted to get yalls thoughts, thank you.
