I just purchased a '71 that has been sitting in a garage since 1976 and hasn't been started since then. In the mid 80's, the engine was pulled and completely gone through and re-installed, but the owner never finished and since it was rebuilt, it has never had fuel or been started. I was wondering if somoene had a checklist that I should go through of things to check prior to seeing if it starts. Obviously, I'd like to put fresh oil, coolant, gas, but what else should I check prior to turning the key?
What do you mean by never finished? And gone through?
Depending how it was stored. I would pull the plugs and see if you can rotate the crank. Use a socket and breaker bar on the front crank bolt. If it is free shoot some oil down the cylinders. You should also prime the oil system. It's a crap shoot for an engine that sat for that lenght of time. But I lucked out on one that sat for 16yrs.

The main thing to check is if the crank will still turn. I picked mine up in a similar circumstance and found that the engine was frozen solid. I planned on pulling it anyway to rebuild it "my way" so not that big a deal. I will say that I had to remove one piston with the use of a piece of 2 X 4 and a big honkin sledge hammer! Make sure it turns. If it does, as the previous response stated, a little oil into the cylinders via the spark plug hole. Turn the engine over by hand to get that oil onto the cylinder walls and onto the rings. I would also pull the distributor and spin that oil pump for awhile with an adapter. Get the oil pressure up and look for oil up in the rockers. Check for leaks. If any gas at all was left in the carb, you'll want to pull it and rebuild it. If it was put on "new" when the engine was last done, you may be ok there. Otherwise, rebuild time. Fuel supply is a concern as well. A bunch of crap can end up sitting in the tank and fuel lines after that kind of time. I would flush and clean the system to be safe. Good luck with it and let us know how everything goes.
