F-head high altitude head?

Fuel has come s long ways since then. I had a John Deere B that had a small gas tank to warm the engine up then you turned the main tank which was for distillate, (low grade fuel). The deuce and a half military trucks would run multi-fuel engines that could burn anything flammable.

Oh yes, I always wanted an m35. It would look so cool with a willys pulled up into the bed. And yes, running it off of vegetable oil would be so neat! The only problem is the fact that it's the size of a house. But they are such cool trucks! That john deere is like a lot of antique tractors/hit and miss engines. That would start on gas to warm up then switch to kerosene for running . (Okay I might have the two backwards but it's something like that).
