Most common one missing is the left rear lifter galley plug. It sits right in front of the distributor drive gear.

I have all oil plugs in. I am thinking that the air space between the pump and filter is suspect. I will backfill and reattempt.
I don't even have 1/2 lift, but the other 1/2 is nitroused.

Update: I removed the filter and turned the pump clockwise. No oil was produced. I tried back priming from the oil filter and tried priming with no result. If it helps, the priming rod has about 5-6 inches of bubbly oil on it when I am done.

That is quite odd, you should get oil pressure within a seconds of priming. I usually pack the pumps with vaseline, but either way there should be pressure in system after abit of priming, there seems to be another problem. Maybe pump to cap there's oil bleeding by/ blockage or something of that sort. Is the engine still out of vehicle?
No, I have allready reinstalled it. Also, when priming I feel the freewheeling then a bit of resistance, but nothing else occurs.

After reviewing my assembly charts, I think one of the rear internal plugs are missing. I recall plugging the block just after taking it off the stand, but do not recall if I got the internal galley plugs. I will pull the engine and confirm. Thanks guys.

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?
As you know it gets driven up the main oil vertical passage from the pump in the rear saddle under the main cap & it needs to b a certain distance up in the block & b between the 2 horizontle "out" passages to the filter & there's a slight recess there for it to seat. You have oil in the pan/pump works/you can feel it catching it's prime w the drill (CW). Sumpin's blocking the flow between pump and bottom horizontle out gallery as the filter is not even getting anything. EDIT take off the sending unit & stick a wire straight down in & see how much depth you have and have a helper shine a light into the lower horizontle passage & see if you see light looking down from the sending unit

I am still stumped. I am thinking that there may be gaskets for the pump, but I do not have any or recall seeing any. Is there in fact a gasket that seats between the pump and the cap, and is there an o-ring that seats on the shaft? If so, then this would be the culpret.
Also, to confirm, I have cup plugs installed under the cam retainer(X2). The internal plug by the oil pump drive, the 2 rear external plugs, the plug under the oil filter, and the cap plug under the rear main. If there are more than that then they are all in.

I don't remember the factory installing a gasket between the pump and the cap , but someone mentioned it above so I think the aftermarket deemed one necessary at some point , can't answer the o ring on the shaft either but that doesn't jog anything in my memory either .
It has to be on the pickup side, it must be pulling air which is why it will not prime. Maybe the pickup tube ofthe pump housing is cracked ? Did you have the pump in the oil during your bucket test ?

did you use a set of main studs or aftermarket main bolts If so look very closely at the pump to stud or bolt clearance They can, and do, hold the pump from seating onto the main cap, don't ask me how I know that

I am curious about this cup plug under the main. When I installed it, I basically installed it flush or slightly recessed. Gathering info about this, I learned that on Chevy engines, the plug is driven pretty deep. Someone here mentioned that there is a ridge to stop the plug at some point. How deep should it really be? And would this prevent oil flow?

want it here to divert oil out to the filter rather than it going straight up to the horizontle main gallery

Is there a stop? Is this why it is not priming?

If that picture is accurate it sounds like you don't have the plug in far enough and the oil is not going past the main cap and the pump is just dumping the oil back into the pan thru relief valve It would appear .

I took the cap off and started driving the cup plug in. There is a passage about 2" or so in. I have not finished assembly to check yet, but will post when I finish. Thanks guys.
Edit: Yep, there was a gusher from the top of the block after pressing the plug in.

I'm dealing with the same issue on my 360/410 right now. Poured in five quarts and it won't pressurize (turning clockwise)
Removed the oil filter and adapter and found it bone dry.
Stuck a rod down the sending unit hole and hit the plug right where it's supposed to be.
I double checked to make sure all galley plugs were installed when I got the block back, so I'm certain that's not the problem.
Reusing this pump from my 340. Looked brand new and worked fine in the old motor.
Running a Kevko pan and pickup. Pick-up depth is right where is supposed to be.
Looking like I need to drop the pan to see what's going on.

I think my problem might actually be with the priming shaft. It was made from a big block intermediate shaft and the diameter is not reduced at the base like it is on a SB shaft. It's not dropping into the pump drive.
I've got a couple SB shafts I can use to make a new one.
Stay tuned.

Turned out my pump was quite seated into the pilot hole. Priming shaft wouldn't drop into the drive.
Dropped the pan and reinstalled the pump. Problem solved.
