Newly Built Engine Will Not Prime

I recently built a 383 stroker and put it in my car. I went to prime it up today and I had no oil pressure.

Yes, I did have the oil pump with vasalene and there is oil in pan. It is a melling high volume oil pump, and I am not getting any oil into the top of the motor. My oil pressure sending unit is on the bottom near the filter and it is also reading 0 PSI.

I am not exactly sure the direction the I installed my oil filter adaptor, but I do not think this could cause the problem... but if that could be a possibility, I would like to know. I am also priming the pump clockwise.

Oil Pressure

My partner had the same problem with his engine....
Builder suggested to remove all spark plugs and crank engine....
Pressure came up right away....
Didn't make any sense that the standard technique of driving the pump with a 1/2" drill wouldn't work, but it wouldn't....

Are you using the correct primer? Just a straight shaft will not work. Needs to be like the distributor. The oil passage goes around the dist housing. If you are using just a shaft and no housing, the oil will get picked up fine but dumped right down the block where the dist. goes.

I made one out of an old distributor I found in the junk. Disassemble it and cut the housing about halfway between the bottom of the main housing and the flange for the hold down. Cut the shaft off just under the head so you have enough to chuck in a drill. Place the cut off housing in the engine, chuck the shaft in a good 1/2" drill and feed the shaft through the housing and turn it until it engages the pump, then prime away.

if you try it with the baffled primer shaft and you still don't have upper oil gallery pressure, suspect the main gallery plugs at either end of the block.
