That looks like a really good project truck and a lot better than many here have started with.
I had a 66' GMC equivelent model, think it was a 4000 but memory isn't as good as it once was. Anyway it was a 305V6 with a 4speed and 2 speed rear. I really loved that truuck it had more grunt than a lot of larger trucks and was in excellent condition back in the 70's.
