Prelube the engine right before start up. Much is made of getting oil coming from all the pushrods, etc. but as long as the pump is pumping (you will definitely feel the drill labor when the pump is working) and you run the pump long enough to pressurize the system (plumb a temporary gauge to monitor the pressure while priming) and fill the oil filter and galleries, that's good enough- as soon as the engine starts there will be immediate oil pressure, and THAT is what's important- that the engine doesn't run w/o pressure. | Prelube the engine right before start up.

| + | For installing a Chevy V8 distributor and setting the timing so the engine will fire immediately, see [http://www.crankshaftcoalition.com/wiki/Chevrolet_V8_distributor_installation Chevrolet V8 distributor installation]. Other distributors will install similarly, but be sure of the [http://www.crankshaftcoalition.com/wiki/Category:Firing_orders firing order and distributor rotation], along with any other details that might be different if another make of engine is being worked on. | ||

You must not idle the engine even for just a minute, so set the timing using a dial back timing light or make a timing tape so you can see what the timing is at w/the engine running at 2000-plus rpm. You can give it 32-34 degrees (not counting the vacuum advance), no problem. Won't hurt to connect the vacuum advance, because the engine is running w/o a load, so there won't be detonation from excessive timing unless you were to go WAY up there. But 32 degrees w/o to as much as 45 degrees w/the vacuum advance hooked up is OK. Placing a large fan in front of the radiator can help. | ||
