If the little barbell looking plug is missing you'll have oil pressure problems. But that usually happens with newly-built engines, no reason the junkyard would pull one from a takeout engine.
You've got good oil and an excellent filter, so they're not the issue.
Did you install a double-row timing set? Check for the extension blocks installed backwards if so.
If the barbell plug is in, and you're positive the O-ring was installed right:
1.) O-ring above the raised ridge on the pickup tube, not below it...
2.) O-ring on the pickup tube before you slid it into the pump, rather than installing the O-ring inside the pump and then sliding the pickup into place...
After these, you're left with either the oil pump failed or the engine was junk when you got it.
