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.
