Max 360 Main Oil Clearance
I've just never heard it referred to as "diametral clearance" before. I wanted to make sure that's what they referred to as bearing oil clearance. Thanks!
The engine in question is a stock 360 rebuild my dad's D100. His machinist polished the crank and said the journals spec'd out just fine with a mic, but since he didn't have the bearings yet, hadn't measured the ID of the main saddles w/ bearings when my dad picked it all up. So now, my dad's putting it together and doesn't have the tools to properly measure the clearance, but was told it'd be fine. He used plastigage and got this (picture below). Looks like a tad larger than .002" to me. Maybe .0025"? Would you run it? The bearings are full groove clevites and he was told by his machinist to buy a standard replacement M72 oil pump. I just don't want him to fire it up and have low oil pressure.
