It would bolt on if you have the same large bore size on your intake.

Been thinking about doing something similar with my 200, but using CNG, not propane. CNG sells for $1.39 per gallon around here...
From what I can tell the setup for propane and CNG are similar except for the tanks.
Has anybody attempted this?

Ran couple propane rig's still have a few parts left. Have not tried CNG though had the chance to buy a CNG compressor unit (3 phase power) for cheap about 8 years ago 
Than there is still the tax deal unless it's used for off road

You would either have to go to a fill station or have a compressor unit to be able to use it from a home NG line if I remember right is only about 5 psi we tested gas lines to homes at 15 to 18 psi. Don't remember pressure output of the compressor unit I looked at guess would be about what a Propane tank is but could be even more. For quite awhile So Cal Gas Co. had quite fleet of vehicles that were powered by CNG.
I'm told the gas lines are about 8 psi. Not enough to fill for 200 miles in 10 minutes, huh? They still have a lot of CNG busses on Foothill Transit and the Santa Monica system. They can turn 20% of the fleet every few years for a lot cheaper than MTA.
I'm thinking home compressor and tank, if doable.

Well, buses are 3600 PSI. Hmm. Need to check on an I6 Ford.

Looks interesting but there are no refueling stations in SoCal. Bummer, dude.
Added in:
Well it's getting real interesting now. Home fueling station with a $2000 credit for CNG car owners. What the heck. Maybe dual-fuel.

Interesting, the unit I looked at was a big commercial one used By So Cal Gas it was 3 Ph so I passed on it. I seen a CNG Ford Fairmount for sale a couple years back too.
They showed a 3600 and a 3000 psi station. Boy I'd sure hate to hook up to the wrong one and get a 'fuel spill'. But that home unit looks real slick. I'm going to look into it. Like I said: dual-fuel with a reserve CNG tank in the trunk. Heaven knows, I sure don't haul groceries in there.
Yep, that would work fine on a 200, 250 or 300 as stock, theres not much more than 90, 100 or 120 hp net to provide gas for.
Regards the picture in the link.
E-series converter which boils the liquid propnae into gas is on the left of the picture....its okay for 270 hp with the nice big CA 225, 300 and 425 Impco carbs for 2 and 4-bbl V8 engines. Fine for any LPG carb on a six, and Impco's best converter in my opinion.
What you have on the right is a CA 125 Mixer, the propane carb that sends the propane gas into the intake port. It's only okay for about 125 flywheel hp. It's fine for a stock 300. Its for LPG (propane) only...for CNG, you use a special Impco CNG carb like a CA 200 or somesuch.
Background is that Ak Millar did a 2.3 Propane turbo Fox Fairmont, a 255 V8 Mercury, and a CNG Mustang back in 1983. Lots of work was done tidying the system into early on board closed loop EEC computers, so its not hard to get a kit to run. The later Command systesm which link in with the oxygen sensor are good with the F150, lots of dual fuel and LPG dedicated systems around.
For dual fuel or sole LPG requirements, there's no way I'd run a CA 125 as it s too restrictive for good performance on a 200 or 300 I6. Good options for a stock six tootling, but really like drinking wine from a shot glass as the CA 125 is only a 202 cfm carb, and little better than the stock 1-bbl Carter, Holley or Motorcraft item that's already there.
You could put a triple CA 125 unit onto an Offy triple carb system, and run it progressive with another 1 000 dollars worth of gear if you were keen.

Both are good clean fuels(LP and CNG)BUT the LP will give better fuel milage because IIRCCNG has less BTU`s per gallon than LP.Less BTU`s= less heat,thus less performance and fuel mileage.Which is why you will get MUCH better performance and mileage with good old fashioned gasoline.Now if I am wrong please correct me.Also,for optimum performance on LP or CNG,the engine SHOULD be purpose built for which ever(LP ar CNG)type that you will be using.IIRC,for LP the compression should be around 10 or 11-1.With CNG,IIRC,around 13-1.Also,here,if I am wrong PLEASE correct me.
Thanks.

Pretty much on the money.
CNG is long term the best bet.130 octane and its everywhere. LP Gas is looking better as it becomes tied in with gas or liquid injection, but the kits will always be pricey as in the old days, LPG and gasoline used similar dispensing systems. Now, there is no direct LPG injection to work in tandem with more modern SIDI/direct injection gasoline engines. LPG tank stepper pumps are getting more complicated,and it looks like the days of these cheap 600 buck propane units is about to end unless we keep our old small and big block in line sixes.
Go ahead and add LPG. I did, and it was the single best addition I ever made to my old 250 Ford
