found in Frito Lay bread trucks. It is turbocharged. Ranging from 105-130 hp stock form. Can easily bump that number though. It won't be a rocket ship, but if I can bump it to 150+ horses, then it should get around pretty respectably. I have a ton of info on the engine if you want to know. If you don't want an overdrive and are just trying to build a crawler, the SM-465 falls in right behind it. That's what most bread trucks had. If it can push around a heavy bread truck, then a 4300 lb bronco should be pretty easy. The engine is about $2000-2500 used with a tranny.
