I use an old corded 1/2" drill that only spins at 900rpm and got 50lbs on the top back port and 75lbs on the side main galley port.
I then switched to my Milwaukee cordless which spins around 1,800rpm and it immediately pegged my 80psi oil pressure gauge. (I haven't check the top oil port with the faster drill yet)
I didn't use the lifter galley oil restrictors per 440Jims recommendation and it looks to be a good decision.
I think KB didn't machine the groove around the cam bearing deep enough on mine. Ken said he was surprised by my oil pressure (with the slow drill); 70 psi mains, and only 13 at the lifter galley. But the oil flow to my heads (via pushrods) was enough as I watched it on the engine stand. Engine worked great (only pushrod oiling to the Indy 440-1 heads, T&D paired rockers).
