Crank bearing oil fees hole size?

[Infidel Edition]

I put the main bearings in and measured with Plastigauge
I'd estimate all at .0015

When I put the uppers in, I noticed the oil feed opening on the block is like 1/4" dia
The bearing opening is oblong, and has roughly 1/2 the opening as the block.
As well, the bearing's opening (all of them) are slightly out of line with the block.

How much smaller of an opening should the bearing feed hole be?
Sorry, I don't have pics at the moment.

OK here's the pics...
Journal 1 right / 2 left
9916
3 right / 4 left
9917
5 right / 6 left
and 5 is like WHY BOTHER....
9918
6 right / 7 left
9919

so would I file the bearing?
....or the oil hole in the block?

BTW~
These are King MB7711SI
I thought King were OK. Do I need to reconsider and go with a different brand?

I would take a look at #4. It doesn't seem to be on an oil journal. It doesn't have to be totally aligned, but does have to be on a hole somewhere.

Did you mean 3 or 4
They're backwards ~ 4 is on the left
3 is the circular opening on the thrust bearing

It's actually fully centered.

The other (same as 5) less than 1/2 of it is open.
With a .002, is 1/2 blocked enough?

If half is open, it is enough. But if you want you can carefully enlarge the hole. The fault is not in the bearing, it is in the block casting.
