Reading oldbulls picture, the tappets and piston squirters get fed from the same galley. All 8 of them were still in place

I don't recall how many pipe plugs are in the side of the block, but the far front plug of the block on both sides would be the cross over, since your not getting much oil or any to the lifters and push rods, I would say that passage is blocked or partially blocked. Take the plug out on both sides and slowly rod it out or blow air thru, see if any debris comes out. I said the oil galleries are 1/2", come to think of it they are 3/8". That passage is drilled from both sides and the drilling don't exactly meet each other, meaning there is kind of a lip where the drilling meets and something can be caught there. The bottom end is probably getting plenty of oil as most of it is going there. You said your getting 45 PSI at the lower galley, should be more like 10 - 15 PSI at idle.

Isn't it more than that on a cold idle?

Wasn't on cold idle. Factory wiring is not hooked up. Running jumper to fss to run it currently

I meant both the engine and oil temp being cold.
