I'd block the oil filter bypass. All that wear you see is being pumped through your bearings when the engine is cold. I bet your main bearings are toast.

Main bearings are fine, bypass is plugged.

That's good news.

Where you take the oil pressure reading also effects the perceived pressure. 15w50 would likely get you to 20 psi at idle and 60 at wot hot. That is plenty in my opinion.

I tried 15/50 didn't help. Pressure taken by three different gauges. Did some more checking, seems to be a distributor/intake height/oilpump and shaft issue.

I've seen that before. Something to ALWAYS check before sticking the pan on etc.....

I run 20w50 in my big blocks.
Always have, always will.

Simple Castrol conventional, never had pressure issues.
