Time required to fill oil galley ?

[Bruce_MO]

I installed a rebuilt engine a few years ago, and the instructions with it from the rebuilder said to allow about 2 1/2 minutes maximum. I had rebuilt my oil pump myself and it always seemed to take over 2 minutes, so I installed a new pump from Brattons. Now it's about 30 seconds. I also bought a beat-up oil return tube at a swap meet and cut a 3" section out of it and installed a 3/4" ID section of clear tubing I bought from Home Depot with a couple hose clamps. Now it's really easy and clean to check oil flow...good view of timing and amount.
