After finally getting everything together and getting it on the run stand, I'm not able to get oil pressure from just spinning it over with the starter. I have included two videos, one spinning it over with just the starter and one using a drill on the pump. It basically shows it takes quite bit of speed and time to get things started. I am using a Milodon pan, pickup, pump and a Meiling pump cover-all new stuff. The videos are after three days of sitting. The line from the pan to pump has a curve to it, where it is higher than the pump for several inches. I didn't take the time to measure the pump, but after this I guess that is my next step.
I looked through several threads and this does seem to be a common issue, it just seemed there was no single bullet-line routing, oil filter drainback, pump drainback, air leak, etc. I didn't plug the internal pickup, as the Milodon pump is solid where that hole is thus it shouldn't allow any air flow.
