bearing clearance?
well i am getting the 352 finished. i am building the short block right now. but have a few questions. the crank was turned 10/10 on the last rebuild before i got it and i have not done any machine work. i have just honed the walls and cleaned the crank. i have .020 for all the crank bearings and .0013 for the piston to bore clearance. do these seem ok?

something like .001 to .0025 max for bearing clearence. Something toward the higher side, i would opt for thicker oil and high volume pump, tight clearences just the opposite. I am not saying you have to do both but i was just listing what options there are.
As for the crank journals, ALWAYS measure them with a micrometer to .0001 accuracy. 10/10 needs those bearings and 20/20 crank needs 20/20 bearings. I surprisingly have standard crank and run .001 bearings if I recall.
