'69 Fargo W100

If it is turning, the old gal will run how good?
Make damn sure all the valves are free.
Use a piece of brass or solid locust draft and hit the top of each valve with a 3 lb hammer.
As for the clutch, the best thing is make sure the brakes are free, push it with a old pos truck from behind with a old tire with no rim strapped to the front bumper of the pos truck.

Get it rolling about 15 mph and put the old dodge in 2nd gear, your clutch disk is most likely rusted to the flywheel/pressure plate.
