Post rebuilt engine no oil pressure in oil galley

I rebuilt a 396 engine. Before assembly I put air in all of the oil passages to blow out any contaniments. Cam bearings where installed properly. I put engine together with new oil pump. When I went to prime engine with oil I get no oil to cam and lifters. You can hear the pump working when spinning with drill. I can take the block plug out by oil filter and it will push alot of oil out. Could it be the oil filter adapter gasket of something like that. (help).
Any help would be appreciated.

Thanks Bill

What year is your 396?, if it's a 65-66 possiblly some 67s you have to have a grooved rear cam bearing along with a cam that has a groove in it on the rear journal. The later engines the groove in the block. Do you know what you have?

The 396 came out of a boat. late 60s. I installed the same cam, it is not grooved nor was the old cam bearing. Any other suggestions

We just went through the same thing, do you have a empty distributor housing? because the oil has to go through the relif cuts to get to the cam oil gallies.... Sounds like everything is fine on the oil filter side because you are able to pump oil out.. you can put another temp oil guage on the driver side front main, it on the lower side next to the oil pan.. that will make sure oil is well on the mains.. we had to spin the pump almost five minutes to get oil to the rockers, bump it every now and then because only the lifters that are down on the base circle will pump up....

Thanks Colaus, I will try spinning the pump with an empty housing to see what happens.

Thanks, Bill

I have rebuilt quit a few engines and most would pump up the oil to the valve train in a minute or two. I rebuilt a chyrsler 273 one time and after 10 minutes of spinning the oil pump like you are doing I still didn't have any oil at the valve train. I thought something had to be wrong. The next day I picked it up again and it took a full 30 minutes until I got oil to the valve train. Since you have oil coming to the filter, you know your oil pump is working. I would keep spinning that oil pump, and I will bet you will see oil where it needs to be. Some engines just take longer than others.

you're not going to get any oil to the rockers without a housing...
