I have read good reviews here over the years. Engines run cleaner, oil doesn't blacken up as bad.
One of the bigger drawbacks is the additional tank & lack of filling stations.
Natural Gas is another source that could be a huge benefit to cleaner air quality.

You might be able to find a scrapped conversion and get everything you need, but it would take some looking methinks....
Less power and more fuel consumption with the propane, but it's supposed to work out to being cheaper due to the lower cost of propane. Best check some prices and do some math before setting out on this plan. First up, how many miles per year do you drive?

That sounds interesting
Natural gas conversion can get pretty complicated but maybe propane would be simpler? it is distilled from natural gas but is liquid after all.
I wonder if an EFI setup would handle it better than a carburetor.

I received a newsletter from FTE last week, one of the stories was on the 2013 Ford WiNG Westport LD :: Ford F-250/350 Super Duty Trucks
Prolly when they hit the streets the price will come down.
Keep a look out Obama will be offering big free bucks for solar powered trucks.

I'm in the middle of a natural gas conversion on my 65 f100 352. Its really a lot easier than I thought it would be. My father in-law sells kits to do the conversion for around $700.00 but that does not include the tank or the bracket for the tank.
The hardest part is drilling a hole in your exhaust and welding on a bung for an o2 sensor.
The system will automatically adjust the AF ration for the best fuel economy, and natural gas is 130 octane so you can advance your timing a bit to get some power back.
Best part is Natural Gas is only 1.50 a gal where I live and fill stations are very common, so I will be able to afford to drive the truck again.
Feel free to PM me if you have any questions. I have installed a few on injected cars, this will be my first carb.

On an efi engine you have to drill holes into the intake as close to the gasoline injectors as you can. then you tap into wiring harness and pull all the signals that are going into the efi ECU into the cng (Compressed Natural Gas) Ecu. then the cng ecu sends the same signal to its injectors that the gasoline ecu would send to its injectors.
The carb Kit in much easier. You just need to build or buy a carb hat and then pipe the cng into it with a cng mixer. Imagine a carb hat with an intake tube and filter. The mixer is a round piece that is the same diameter as the intake pipe and you just put it inline right before the intake pipe. The flow of the cng is controlled by what is called a stepper motor and that is controlled buy a really simple computer.
If you can read really basic wiring diagrams then you could wire it in.
I didn't realize that this forum doesn't a PM function. If you get me your email address Ill send you some pictures of my install so far. Its kind of on hold until I can get some clutch issues figures out But i can send you what I have and it will give you a better idea of what Im talking about/
Almost forgot. Performance is about what you get out of propane. Expect about a 10% Decrease in power. How ever this can be made up by putting in a timing advance actuator that will automatically advance your timing when ever the kit is turned on.

I am considering a kit I found somewhere (don't remember were, it's saved on my other computer though) that allows you to start the engine on regular unleaded, then switch back and forth at will with the flip of 2 switches (one to turn on the mixer hat that sits under your air cleaner, the other to turn on and off your electric fuel pump), was just wondering the pros and cons, and how hard they actually are to install and tune. And maybe some tips as to how it's done

Most of what you find is converting stoves on sailboats....
From what little I could glean, the CNG tank won't work for propane. Valve is in the wrong place, I imagine the filling device is different as well.
