Oiling question
I have just got my engine together to the point that I tested the oil pump to see what kind of pressure I was getting (@ 60lbs with cold oil). I noticed that the area where the distributor gear sits remained dry after this test. This does not seem right to me. Should I be worried? Where should I look for an issue?

I believe there is a galley plug with a small hole, sometimes it gets left out, no oil pressure or one is installed without a hole, which could be your case. Make sure yours has the hole in it.

There is a plug with a .040 hole in it for oiling the distributor Gear .non olds builders are notorious for removing them and replacing with a solid plug .when I preprimed my engine I could clearly see oil squirting from that area . It sucks that you have to check the work of your builder but it’s sometimes necessary.

You should definitely have oil squirting out of the hole when turning the pump over to prime or check for oil pressure....
Get a mirror down the hole and see if you can tell if there is a hole in the plug or not....
If there is a hole, your machinist may not have pulled that plug from your block, and when the block was cleaned or hot-tanked, the crap from your oil galley likely stopped up the oiling hole.
If there is no hole, as others have said, there must be a plug with a hole in it to oil the distributor gears. If yours doesn't have one, you need one to keep the distributor and cam gears alive.
If you can get some welding tip cleaners down there, you may be able to poke through the hole and clear it out, which should let oil through..... but, the crap that was plugging the hole may stick back in it, so I recommend pulling that apart to clean the plug completely and reinstall.

Thanks all. I was pretty certain There was an issue. The machinist replaced the plugs after installing the cam bearings. Not a huge ordeal since I still have the engine on the stand. I'll pop the plug out and drill the hole in it and replace it.

Turns out that the plug did NOT have the oil hole. Glad I caught that! Removed it, drilled with a #60 bit, chamfered the back of the plug at the hole with a 3/16 bit and she now flows oil!
