I'm thinking ahead to first fire of my engine (347 stroker, Edelbrock EFI) and realized that since my intake hangs over the distributor, my assembly order must be 1) set distributor, 2) install intake, 3) install and connect the wiring harness from the firewall ECU plug to the engine, and finally 4) apply power, check the ECU readouts and hit "Start". I do have an oil pump shaft to spin the pump with a drill, but once I spin it there will at least be a delay time to get things installed. I'm thinking that I need to spin the pump, and at the same time rotate the engine with a breaker bar to get the internals well coated with oil, then set it at #1 TDC compression. How long is this "drill prime" good, in your mind?
