I just found a cab and chassis along side the road in a farmers field with most everything still on the truck. So I stopped to see what was left since it had been retired many years ago...I noticed it still had the dash cluster...Then I noticed it was the detroit under the hood...The dash cluster had the factory air gauge and a factory diesel tach which went up to 4k. Way cool! It also had the radio delete...I could not find the owner so maybe I will check it out on my next trip.
A good friend of the family bought a 70 GMC 2 ton and 70 GMC 1/2 new for his business. The 2 ton had a 350 2bbl with governer. Excellent motor for hot rodding as it had the 4 bolt mains and even thought it had the 2 bbl it had large valve heads. Only problem with the small blocks in the bigger trucks is they worked there ass off and rarely saw 50k miles before needing a rebuild or replacement as the rods tended to exit the oil pan when the engine was done.
