What all should I do (not including anything regarding fuel, oil, coolant or battery replacement) to get on old 68 GTX started after roughly 12 years of being garaged?
Also, where would be a good source for wiring diagrams?
Any tips would be appreciated. Thanks.

 

Need more info;
440 I'm assuming.
Does the motor turn over by hand?
Is everything still hooked up?
Have you changed oil/filter, flushed fuel tank/lines/filters, new battery, replaced points/condenser/plugs, changed trans fluid/filter, flushed coolant and refilled, check brake fluid, rear diff fluid, new belts/hoses, ?????
If these things are done, I'd prime the oiling system and fuel system and fire her up.

 

I agree with ZP !!!

 

great post.

 

In addition to the above, I'd pull the plugs and squirt about a teaspoon of engine oil into each cylinder and crank it over for a 10--20 seconds before fire up

Don't forget the transmission!!! If stick, check oil level. If auto, check oil level, run for 30 seconds or so and make sure it will go into gear.

When filling / flushing coolant, be wary of airlock. "The way to do that" on old Mopars is to pull off the heater hose on the T stat connection and fill until you get coolant out the fitting, then hook hose back up and fill to proper level in radiator.

When firing up, check heater hoses for warmth, indicating proper circulation. Obviously, heater controls must be selected or heat.

 

Lift each wheel and turn by hand to make sure none are siezed. Maybe remove drums to be sure they won't sieze the first time you use them. 12yrs is a long time for brakes to sit unused.

 

west -

Oil the cylinders, WD-40 through the spark plug holes, and then turn the motor over a few times with a breaker bar on the crank nut. If it turns odds are you're good. If not, let it soak over night and repeat. If it still doesn't turn, you're looking at a tear down.

If you don't have mice or other vermin in the garage, the wiring will probably be fine.

It may be a good idea to pull the distributor (marking it's position), and spinning the dizzy gear to get the oil flowing.

After the engine has been turned manually and the oil primed, replace the distributor (making sure it has the same orientation as when you took it out) disconnect the coil lead and try the starter, with the key or a remote switch. If the motor turns, so far so good.

Unless anything looks or smells funky, drizzle some gas in the carb and try to start her up. Keep an eye out for fuel.oil leaks and listen for vacuum leaks.

Do a google search for wiring diagrams on your car, and more will come up than you'll know what to do with.

Obviously check the trans, diff, break fluids etc.
