Converting gas to LPG

Hi all, I'm looking to convert my 1996 F250 (fuel injected 460) to burn propane instead of gasoline, or possibly making it a dual fuel vehicle. I know it can be done on carbuerated motors, but I'm having lots of trouble finding info on fuel injected conversions. Any & all help would be greatly appreciated. Thanks!

Maybe go to a propane dealer and ask if they have some kind of converters or valves you might need.
