I would change the oil first. Then pull the coil wire and plugs and spin the motor with the starter and see if you get oil pressure. Once that is done stick some plugs in it, new ones would be a good idea, reconnect the coil wire, put some gas in it and see if it will start. You may need to pour a little gas down the carb. If it does start check for leaks. THere is a good chance that the fuel system may be a little gummed up after sitting for so long, so a carb rebuild is probably a good idea. But you may not need to do that to get it started.

I am guessing Odessa is in Texas, and since the car has been in a garage, I doubt you have any worry about a cracked block. Do make sure it has coolant/water in the radiator though. Once you get it started you should do all the routine maintenance things, incuding flushing the cooling system, changing transmission and rear end lube, checking brakes and steering etc.

Good luck with your project, keep us posted.
