LA 360 - 0.030" Undersize Main Bearing Clearance Questions

Newbomb Turk said
Nothing wrong with a .030 under bearing as long as the clearance is correct.

You’d throw **** away real engine builders would use.

You do realize some guys turn Chrysler rod throws down from a hefty and stupid 2.75 journal (unless you are burning fuel) to 2.200 don’t you?

That’s a .175 UNDERSIZE.

I know a lot of guys who have built a lot of engines and I can't remember any of them using a crankshaft that was turned 0.020". Myself, I wouldn't use a 0.030" under crankshaft, but that's just me. The OP said that he had a hard time even finding bearings for it.
