    How do you prime a LS1 after its been sitting for several months? I've got an old distributor that I used to use with my chevy engines, but this thing doesn't have a distributor!! HELP!!

    There is no way to prime one. The oil pump is driven off of the crankshaft. If you are really concerned you can pull the spark plugs and crank it for 15 seconds or when the oil pressure gauge starts to register. A couple months should be no problem. Cars sit on dealer's lot longer than that without being started. Your only other alternative is to buy a remote oil cooler adapter and use air to push a reservior of oil through the galleys. I would not worry about it, personally. Pull the plugs and crank it if you are worried.

    you will be ok! Fire that bad boy up! Just keep an eye on your oil pressure gauge, if it does not register in a few seconds the turn it off! :

    When I did mine I just left the fuel pump relay out and cranked it until it read oil pressure, then reinstalled the relay and fired it up.
