Impco LP Gas
Just got my 1972 F100 converted to run both on gasoline and LPG.
Must say it runs very well.
My motivation to get it installed is money: LPG costs about 1/3 from gasoline over here in Holland, you can get it at almost every gasstation, and because the car is older then 25 years I don't have to pay the higher car-taxes for cars equipped with LPG installations.
LPG is also cleaner then gas, so because of all your emission laws in the U.S., is it used also over there with you guys? Or isn't it as widespread as in Europe?
I've put some pictures of it in my gallery...

There are a few conversion's here (USA), but the avalibility of the LPG gas isn't that good tho. The prices is not that much cheaper than the gasoline here either. That makes takeing a long trip in a LPG vehicle very difficult.

In the North East propane is sort of common for trucks because people heat mostly by propane and wood, so it is available at gas stations in the rural/wooded sections of states. LPG is fairly rare every where.

Since we are on the subject of propane power:
How does the efficiency of lpg compare to gasoline?
What is the difference between propane and natural gas and can they be interchanged?
This has been on my mind just waiting to break out.

From the IMPCO catalog:
Natural GAS: 750-1150 BTU per cubic foot
LPG (Propane): 2500 BTU per cubic foot
What I understand out of the impco catalog, combustion engines can run both on natural gas and propane, though because of the lesser energy in natural gas, it is used compressed. Propane is only stored compressed (liquid) and evaporated before going into the engine (as in my F100's setup).
So they cannot be interchanged on the same installation, a different setup is required. Here in Utrecht they run City-Busses on natural gas, while most cars run on propane.
