Unless you are into larger trucks like I am, there is not much incentive in restoring larger trucks. I have been in the trucking business for 51 years and I own a dozen larger 50's GMC. The cab, motor and radiator are about the only thing that will fit a pickup. If it is indeed a 302 and the cab is in good shape, the parts are worth as much as the whole truck. However having a vehicle with a title makes it a lot more valuable to someone who wants to restore one.
