And once you have the proper tool with collar, make sure you use a GOOD drill, or you'll burn it up. It's still going to take several minutes to prime the top end and the drill will be working against some oil pressure.

Remove the distributor..

Install an oil pressure gauge, if not equipped. ANY rebuilt SBC should have an oil pressure gauge. (if not equipped).

Run your primer, and your gauge will show pressure. That's all I did.

This should be trivial.

spin the crank

turn the crank as you prime, plugs out, get a helper, mechanical pressure gauge to see oil pressure, use the port on top by distributor so you can see the gauge. hmm rebuilt engine with old pump(not me, no way). (missed gasket on oil pickup? sucking air) I would not fire it until I see good pressure for 10 to 30 seconds

^^This. Keep priming until you see oil coming out of ALL of the pushrods. You have to turn the crank in order to oil the valvetrain on both cylinder banks.

Pumps are cheap...but they are pretty much bulletproof unless it sucks something into it. No part is lubed better for sure. An original housing is probably stouter than most replacements.

I always put a new pump on when rebuilding a engine. IMO its the smart thing to do.

This is what I've used and I pulled a valve cover to verify that oil was coming up the and lubricating the rockers.
