Rumble fish: Forgive me OP if I am hijacking, but since you know and I don’t know I thought I would ask. How exactly do you prime the oiling system? I have a 318 engine that’s in a car that has about 3000 miles on it but it has been sitting for about four or five years. Do I need a specific tool to put into the drill (which way do I turn the drill) or can I take an old distributor apart and use a distributor shaft in my drill to turn the pump?

Not the distributor shaft. Rrmove the gear from a intermediate shaft. Then weld a long Bolt to the top of it cut the head of the bolt off. Chuck it in the grill and spin it.
If you spin it backwards you will hear it blowing bubbles into the oil.
