LPG (propane) conversions???

[Big69C20 Toy]

Hey all i've been doing some reading and was thinking about doing this to my truck. Anyone out there done it and have some imput? From what i've read you lose up to 10%power, and get slightly worse fuel economy due to the difference in BTU's. However i figured that since the octane rating on propane is 104 i could put some big pistons on that'd kick the compression up to around 12 or so and it'd be safe. Perhaps a turbo as well or a supercharger? That'd get performance going. I know the engine lasts longer with propane running.

Sorry for rambling just looking for any imput out there on whether or not i should do this. It'd be nice not to destroy good ole mother with my truck. The LPG burns WAY cleaner and the conversion seems very simple.

Thanks for the imput,
Greg
