Incorrect, but thanks for trying. Main & rod bearings are slightly larger than the journal, when bearings are seated in the journal the tension from this holds them in place. Then when you set the crankshaft in place and torque the block halves to the correct value you will get the true clearance. Anything else is just guessing.

It's no wonder there are so many failures on "garage" rebuilds for this engine...I'm still 0 for 150+
