The only test I can think of is to remove the timing belt and soon the intermediate shaft with the engine on a stand, using an electric motor and an ammeter to determine wattage required with and without the oil pump attached. Once I get the other motor on the stand to rebuild, that might be an option.
3600 rpm is a decent speedfor a test, because it would be in excess of 70mph road speed, and is likely the highest speed the engine will regularly see.
A motor that spins 3600 @ xVDC with an ammeter to read current draw should give enough basic data to form a conclusion, yes?
Test 1: Intermediate shaft and oil pump installed, sae30 oil.
Test 2: remove oil pump pickup, leave pump installed (bearings well be oiled fromm previous test.
Test 3: pre oil bearings, remove pump and spin balance shaft alone.

You'll probably want to use a speed closer to road load unless you're always going 70mph. An ammeter/voltmeter may present a small problem since motor efficiency changes with load/current, but with the caveat that any results will likely be exaggerated by a bit it should be informative to run a test like that.
