propane powered amazes so many of you yet the namesake to our forum has a natural gas powered vehicle in their lineup. granted its not propane but very similar. gm also had propane powered 1/2 ton pickups for quite a few years. the biggest thing that has to be changed is in the heads and obviously your fuel system. theres many diesel applicatioins that use propane. its really not that difficult of a process to have a propane powered vehicle.
