I have another post related to this but I need another point of view. I have my sbc 400 out of the car w/ the intake and heads off. When priming the engine should the amount of oil that comes out the oil pressure sending unit port behind the distributor 'If you had it unplugged" be the same as if you had a oil gallery plug unplugged?That's what I'm trying to nail down here.
I would think that it should come out of the rear oil gallery hole like it does the oil pressure sending unit hole. But it doesn't it just kind of seeps. The same with the oil gallery hole that's inside the block right inside where you prime the oil pump on the rear side of the block. I'm wondering if I have some sort of restriction in the oil gallery.
