I drove a similar truck just across my state to Tennessee, It burned a set of points and had over-heating problems.......... To drive an old truck the distance you are talking, you would have to stock up on a few parts, (I would anyway) like an ignition module, ballast resistor, points and condenser, maybe flush the radiator and change the water pump.........
Hot Rod magazine editor and Road Kill host Freiburger has rescued a few cars from the desert and drove them to California, so a car that has been sitting a while making the trip is possible, if you take the proper precautions......
By the way, I love the old sweptline trucks, and will own another one day..........
