Soooo....the 40ish psi at 2000 RPM was an anomaly. I've been fiddling with the oil pressure for the last half of the day and now the pressure reads 10-12...all the time. Pulled the dizzy, chucked my priming tool into my drill, and pressure reads 16 at the highest speed (checked with two pressure gauges). Oil pump is shot.

Gotta love getting problems solved (carb and radiator) only to have another problem present itself! Better in the shop than on the road though.

That was YOUR idea from a previous thread!
Going to order the Melling tomorrow. I'll definitely get the plastigauge out and check clearances, hopefully everything is okay.
