Pressure pot pre-oiling 235?

[4d9r]

My 235 has been sitting inside for a few years after logging 3K miles on a fresh rebuild while I'm rebuilding the truck. I'm, of course, going to pre-oil it before I fire it up again but I'm wondering if I could use a pressure pot in the oil galleys instead of pulling the dizzy and spinning the pump? I know they do it on rebuilt plane motors and I don't see why it wouldn't work on the 6.
Here's the idea -
I removed the after market canister oil filter because it only filters about 15% of the oil and it is, in my opinion. a source of a potential hazard if a line breaks. I'm fine with doing 1000 mile oil changes.
I plugged the oil return line on the block and fitted the pressure port with an oil gauge.
Now I want to use the port where the gauge is to pre-oil by getting a bladder type pressure pot, filling it with oil and using 30-40# of pressure from my compressor to push this oil through the galleys, lubricating the bearings.
Any comments/suggestions?
