Thanks for all the messages. I have not settled on how to finish the truck. Right not I want to get it running. It was in the posession of Dunn Chevrolet until November 2005 I am told. I spoke to Mr. Dunn. It changed hands twice? I bought it from the second fellow on ebay. I had to call Mr Dunn and get a letter from him when trying to get it titled in Pennsylvania. His father had a small collection of cars as well that I am told he sold off.
I believe that it still has the same oil and coolant in it from when it was last tagged in 1976. The PO ran it and it ran to get on the truck. I have tried to start it, but it will barely turn over. It turns very very slowly, like a battery that is almost dead. I bought a new 6 volt battery and it didn't help. So I am planning to change the fluids, rewire it, figure out where all the brake fluid leaked out and maybe rebuild the starter. I will probably convert it to 12 volt. If I get all that done, I will probably drive it as-is for a little while and think about my options. I will keep it garaged in the mean time.
I think that the motor is a 235 out of a 53 passenger car or so I am told. The head appears to be newer as in 54-56ish. I am going to try to dig up the casting numbers.
