I have just been offered a C70 with air brakes and a Gmc V6, I also have access to a 51 2 1/2 ton thats rough but complete, I have a 48 one ton as well. I want to put the V6 and rest of the drive train from the C70 in the 2 1/2 ton and the 48 cab on it and use it as a tractor to pull our pulling tractors to local events. The C70 has been used as a plow truck and is really rusty but it runs like a clock. I think it would look really cool with lo pro 22.5's on polished budds on the front a small sleeper and air ride in the rear. I also have access to a 13 speed road ranger which would help the V6 on the hills stay in its torque range, gas mileage would be attrocious but I wouldnt be going much more than 30 to 40 miles a few times a year any way. It would be cool to see something different than the usual Mack B models I usually see, I love B models but this would definitely be neat.
