No oil pressure on my 70 Cutlass 350ci
I started a thread on Facebook about 7 weeks ago (I had to finish installing power steering in my 58 Impala before I started to work on my Cutlass) and I received a lot of replies on it from removing the engine to replace the oil pump without pulling the engine out. One reply was to remove the distributor and spin the oil pump shaft to see if I get oil pressure and low and behold I had oil pressure on the factory dashboard gauge. My next step is to remove the oil filter and cut it open to see if there is any broken pieces inside. Any opinion on how I have oil pressure when I used a drill but no pressure when the distributor was spinning the shaft.

350ci Rocket, Oil level was fine. I started the car to go for a drive and I heard the lifters making a noise. Day earlier I drove 40 miles on it. Drove in the garage with no lifter noise, next day lifters were making noise.

Now how much pressure was generated would be my next question.

OK. I got a little ahead of myself. I have several things going on around the house. The oil pump shaft must be engaged in the camshaft intermediate shaft (I called it the driveshaft) which connects to the oil pump. Sometimes the intermediate shaft comes out w/ the distributor - other times not-so-much. The oil pump intermediate shaft might have slipped out of place at some point if the distributor was removed and/or replaced. With the distributor out look down the hole with a flashlight (tough to do I know), you should see the top of the shaft, it looks like the head of a regular flat tip screw. I'm not sure what you used to spin the intermediate shaft when you pulled the distributor - I'm assuming a hand-held drill? I'm confused how the drill spinning could move oil but the distributor does not. So I was thinking the bottom of the distributor is not engaging the intermediate shaft to turn the oil pump possibly?

Ah well, you beat me Kenneth. When I said driveshaft, I meant the intermediate shaft; and, yes, the key-way at the bottom of the distributor might not be engaging the intermediate shaft. I said driveshaft by mistake, meant to suggest the intermediate shaft.

Kenneth, you're probably correct, it might be a hex, instead. I thought earlier distributors had a different key. At any rate, agree that key needs to engage the intermediate shaft.

this should indicate your oil pump driveshaft is ok, since you spun it from the top of the hex, and it turned the oil pump and generated pressure. I am not sure what advantage there is to pulling the drive shaft for inspection. I would inspect the distributor to ensure the gear and the recess for the drive shaft are ok.
Now how much pressure was generated would be my next question.
