Normally you want the oil feed at the 4:00 location. That's an SAE standard for where you want the oil wedge to support the camshaft in the journal. With the bearing being grooved on the back, the oil will travel around the bearing and will oil wherever there's a hole. Not sure why they put 3 holes in the bearing, but in addition to the 4:00 position, it will oil in 2 more spots.

Final wash is done, painted with Duplicolor semi gloss black engine paint. Freeze plugs and galley plugs are in.





Picking up the rotating assembly from the balancer on Monday.

I thought there was something missing!

Got the rotating assembly back. Checked main bearing clearances and they were too small for my liking, so I'm ordering a set of "X" bearings.
