I missed the word inherited. I was thinking you bid and bought the unit at an auction. Guess I watch too many shows!!
Do this first. Get it running, driving, and stopping with the six cylinder. Drive it for awhile and then decide what to do from there.
You won't have a ton of money in it. Best would be an engine rebuild, but you might start with just changing fluids and ignition (plugs, wires, ballast resister). Trans fluid, new fuel. Master cylinder, have the brakes gone through, new tires.
Those engines are decent enough on gas. Drive it for several months and then decide. You just may enjoy it enough to jump in and do more!!
