Sounds like a nice setup. I used to have a '66 Scout with the 152 ci slant four in it. I miss that old truck. I always thought a six would be nice in one of these. From what I have seen, the sixties/seventies Chevy trucks had either Rockwell(don't know the model number) or New Process 205 transfer cases in them. I've seen them both ways. I don't know much about the Rockwell, But the NP 205 is a very good case.
