starting motor that has been sitting for 20 yrs

Hello there friends
I have about finished all the work on my 47 ford truck,from engine ,and also a new paintjob ,and I did it all myself,im glad it is over.
The question I have is im buying a 69 corvette from a guy at work and it has been sitting in his garage since 1984 ,and not started,I am wondering what I should do to the engine before I try to start it.He put on a new gas tank ,and gaslines before he put it in his garage 20yrs ago so there wasnt any gas in the tank at all.Any sugestions would be appreciated .

thanks guys Bill

Personally I would put a small amount of oil or lubricant into each cylinder, turn the motor over a few times by manually cranking the engine over (suppose you could unhook the coil and let the starter do the work), then I would remove the distributor and use an adaptor and drill to prime the engine oil, might do a general tune up and go from there. I would think your seals could be in poor shape, but who knows? Thats why I said I would go from there a.k.a. see what leaks, haha, good luck.

Pull the sparking plugs, inject some oil on top of the pistons. Spin the engine over with the plugs out til the oil pressure goes up. Install plugs. Replace all coolant system hoses and install new a/f 50-50 mix. inspect belts, replace as needed. Flush brake system-probably need new calipers/wheel cylinders, and shoes & pads. don't forget the wiper blades.
Drive.

Usually when a engine is to be stored that long, a fogging oil is used in the cylinders to keep them from rusting up, you should verify that this engine was put into storage properly so that you are not buying something that might just need rebuilt.

But, remember, this is a Chebby.... mebbe they dint make fogging oil for that brand. Chuckle.

Actually, I bet most people that end up storing a car for that long do not think that it will be sitting for more than a few days or weeks at the most. Unless they planned on creating the 'old car found in a barn' scenario. I know my pop stored a car that he was actually trying to sell, but sort of lost heart when he found out how much depreciation he was getting. He did nada. Of course, that was back when FoMoCo didn't have any engines with hydraulic lifters, nor any other fuel system than a carb, so not much got messed up in his case.
I'd bet on needing the rebuild, myself.
