Understand about life, it constantly jacks with my available "Duster time"! That's very low oil pressure. I assume that's a mechanical aftermarket gauge and not a factory gauge (without going through 4 pages to verify) reading, correct? The old standard is 10 psi for every 1000 rpm, which still seems too low for me. That would indicate worn out bearings and excessive clearance. I don't know what oil weight is in it (again, without going through 4 pages to verify). If you don't already have 20W-50 oil in it, add some of that and see if it pops up the oil pressure. You could even throw straight 50W in if you can find it. Only recommending this thicker oil to verify loose clearances. Before you change any oil, run Sea Foam in the oil to clean out any carbon build up in the motor. Doubt it will help with the oil pressure, but it definitely won't hurt and might free up carbon build up in the piston rings and lifters. Get the motor up to operating temp and vary the rpm. I don't drive the car when doing this cleaning. Do this a few times and you'll be surprised at all of the crap that comes out when you drain the oil. Let us know if this helps with the oil pressure. If not, it might be time to pull the motor and check oil clearances, using plasti-gauge, on your rod and main bearings.
