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?

Sounds good.

Why not pull the spark plugs squirt some oil in each cylinder and hit the starter till you get oil pressure then install the plugs and start it.

This will lube the cylinder walls which would be the driest after sitting for a long time and lube the bearings without a load on them.
