tore engine down after having same issue but op dropped to zero when ever driving found damage on center 4 piston bearings replaced with new factory sized bearings did not check oil clearacne as motor only had 30k miles on it and everthing else looked brand new damage was from me cranking with out pre lubing
I don’t prelube my builds. GM doesn’t either. That’s what assembly lube is for, otherwise we’d build them all dry. You’ve got clearance issues somewhere in there.
Prefill your oil filter and fire it. It will have oil pressure in 1.5-2 seconds.

No telling man it could be a number of things causing OP to drop off. Seeing a little material on a fresh build is not uncommon though. Are you sure you have the right o-ring on the pickup tube? Is the screen on the oil pickup clogged? Is there a problem with the oil pressure bypass valve on the oil pump? Of course bearing clearances is another one. I'd try a quality oil filter and some 5W30 and report back.
