1950s 365 oil pressure

The really good news is...you didn't wipe out your new engine.

Update time. It still doesn't work.

The old and new pump will both pump oil on the bench when I turn them by hand.  So I mounted the new pump to the block, and with the pan off I submerged the pick up in the same container filled with oil as I had on the bench. I spun the drill and I could feel the pump fill with oil and the level in the container dropped a bit. Just enough to fill the pump. 

No pressure on the gauge. No oil anywhere else in the block.

With the drill stopped, the oil runs back out of the pick up and into the container.

Im out of ideas with this.  Im thinking I might as well cut my losses and sell this engine and buy an LS with whatever I can get for it.

The guy I bought it from said his car was cursed. Im starting to believe him.  His car didnt run right because the engine was trashed. He bought this engine and rebuilt it. It was freshly machined, all new parts. He gave me all the recipts and I even spoke to the shop that worked on it. He couldnt get it to work. The shop is stumped and now Im also on the ropes. 

Unless one of you guys has any ideas Im just going to throw it on marketplace and see what I can get for it.  Summer is coming and I dont want to waste any more time chasing wild geese.

I'm wondering if the oil canal is blocked by dirt or whatever which could avoid to let circulate the oil? Did you try with compressed air to blow into that canal?
Another try if posible: remove the rear cap to see if the bearing shell is the right one?

I have the same thinking. There are only so many things it can be. With the pump working, the next thing to look at are the oil passages. You can either use compressed air like Roger suggests or they make long oil gallery cleaning brushes you can buy. I know many people who, unless they have their engine professionally done at a machine shop, don't bother cleaning any of the oil passages and you'd be amazed at how full of debris they can get.

If you're near Florida, I would be interested in taking over the battle.

Rogers' suggestion of pulling the rear, or possibly the front main is a good one.

I rebuilt a 346 years ago and had no oil pressure. Crank had been turned .020"under. The bearing set I received had front and center shells .010": over, Took a while to figure that one out. A call to Egge resolved the problem.   

I use an air drill with a regulator, Spins faster than an electric or a cordless drill.

Does the engine turn over freely and have you tried spinning up the installed pump while turning the engine over slowly?

Remember, it ran a lot of miles before the rebuild. Something is missing or not installed correctly. It's easy for the improbable to become the possible.

THese suggestions may not help, but might help eliminate the improbable.

Lesson learned: Trust, but verify. I should have taken the time to PLasiGage the rods and mains when reassembling the engine.
