The Stovebolt Site Forums The Parking Lot Big Bolts '51 GMC 3 ton's finally mine

I guess you got me on that one... I thought it was the 3 ton but I think I mistakenly listed it as the 470. Now I'm not sure :0. The code on the engine block shows a270783i87 and the serial number shows HC453 10746. That's about as much as I can tell right now. So, I don't have an answer. I guess I can do some more research and get back.
