Are you turning the crank while priming? It was suggested above and you have not mentioned doing that.

I turned it 4 full revolutions during priming attempts. Apparently, I think I may have to tear down and look at the block again. When the block returned from the hot tank, I spent alot of time cleaning out the galleys and passages with brushes. I tested the pump with a drill out of the vehicle in a oil container and it worked well, so I know the pump works. Lets say I did miss a plug. I assume it would be caused by a plug between the pump and the filter which only leaves the one that can be accessed through the vertical orafice directly under the sending unit, correct?

I don't even have 1/2 lift, but the other 1/2 is nitroused.
