Can't beat the sound of a 2 stroke detroit. I just scratched the whole idea, the idea was find a 4 door 720, make it 4x4, turbo diesel, and able to run on waste motor oil. For several reasons, I have scratched that idea. too expensive, can't find a turbo diesel thats both light and has decent power with a mechanical injection pump. And I also already have the Cummins, that is 4x4, I'm just gonna soup it up for long Datsun retrieval and/or hunting trips out west. I already have a long bed 720 project, and a KC 620 race truck project. Not to mention I wanna restore a stockish 620 KC for my old man. He's 80 this year and isn't too crazy about aftermarket stuff lol.
