Testing Oil Pressure On A Big Block 440

Sorry, I get easily confused. Were you going to start it to test the oil pressure? Which plugs? Spark plugs, no. But it won't start without spark plugs. All oil galley plugs, yes.

I generally have 60 psi plus when turning the oil pump priming tool with a hand held speed wrench. A drill motor isn't needed.

Not starting the engine yet. Just wanted to be sure of oil pressure before the start. The 5/16 hexshaft run counter clockwise in my cordless drill bottomed out the pressure gauge. Oil pump works fine.
