LA 360 - 0.030" Undersize Main Bearing Clearance Questions

So I can say I contributed something I like lots of clearance so when I get a crank cut I tell them to cut .011, .021, .031, etc. if you are a little loose you will know. But if you are a little tight everyone will know.


The way they are making bearings today I have to tell them mid size everything.

I used to have to go .001 or a bit more under the low side just top get .0021 on the rods and .0024 on the mains.

Now if I do that I end up with .003 on the rods (or more) and .0033 (or more) on the mains.
