Its a Ford, It'll run.
If they drained the coolant, it will be in better shape probably. If not, there may be some problems.
Pull the dipstick before you do anything and see if the oil level is normal to low. If its high, then probably some coolant got in, in which case there might be trouble.
Plan on replacing the carb with a rebuilt, along with the fuel pump and water pump. Probably not over $120 for all three.
First, Drain the oil and put in a decent to cheap oil. Its not going to be in there long.
Get a oil pump driver rod, you can make one out of a screwdriver, pull the distributor, making note of where the rotor is facing. Put the rod down through the hole and spin the oil pump with an electric drill.
I would run it for a few minutes at least.
In 67, it probably had electric gauges, but if they are mechanical, watch for oil pressure.
It should come up to about 40lbs or so. Then go ahead and put the dizzy back in. It probably will not go first time.
You will have to turn the oil pump by hand until the slot lines up with the bottom of the dizzy shaft with it pointing the original direction.
Pull all the spark plugs, making sure to mark where the wires go. Pour the tablespoon or so down each hole. Too much is better than too little.
Put a big breaker bar and socket on the crankshaft nut and see if the engine will move.
If it will, then turn it over a couple of times. If it turns ok, then put some rags over the plug holes to catch the oil if some comes out, put a good battery in it, and jumper the solenoid to spin the engine over a few times.
At this point, if all that works, then you are ready to start thinking about cranking it.
Drain the old coolant out and check the hoses. Most likely they are rotted. If so, replace them along with the belts. Then refill it with good water. Never mind bout coolant yet.
Buy a new fuel pump and some fuel hose that will fit the fittings. Put on a rebuilt carb.
Warning, watch the air cleaner!
If its a large round flat top unit, unscrew the wing nut on top and the cover should lift off and you will see a paper type filter in there.
BUT, if its a really thick unit with a sort of a hat on top, be careful when taking it off.
Its an oil bath air filter, and has about a pint of motor oil in it which will spill everywhere if you tilt it.
Replace the fuel pump, checking the line from the pump to the carb and replacing what is needed.
DO NOT hook the fuel pump to the line going to the tank.
Run a hose from the intake of the fuel pump to a separate can of gas off to one side.
Make sure its a good distance from the engine, and the area is well ventilated so no fumes can build up.
Hook the battery back up, run the coil wire over next to a ground, and see if you get a spark when you turn it over with the key.
If not, pull the cab back off, and clean the points with a piece of cardboard. If so, then put the plugs back in.
If the plug wires look halfway decent, reuse them for now.
If its the paper type cleaner, take the top off, pour about a half teaspoon in the carb and put the top back on.
If its the oil bath, just leave it on.
If it has a choke knob, pull it out. Don't bother pumping the pedal at first.
It will take a couple of seconds of cranking to fill the carb. Then pumping will help.
Have someone watch for trouble, then crank her up. Once it cranks, let it idle with the choke out for a couple minutes. Don't rev it too high at first, wait for all the smoke to get out from the oil in the cylinders.
If you don't hear any bad noises, after a couple minutes, ease the choke in some, and let it run until its fairly well warmed up.
At that point, I would shut it off, see if it will crank again, then turn it back off and change the oil and filter while its warm and any crud is still in the oil.
After that, when its cooled off, its time to drain the water, change the water pump and put in some antifreeze. Don't forget to change that little hose on the water pump.
Then you can drop the tank, and get it cleaned out to remove the old gas, crud, and rust.
Be sure to replace any rubber fuel lines, and blow some compressed air through the line going to the pump before hooking it to the pump.
390s were good engines. With 60K on it, it should be loose enough to not have frozen up while sitting.
