Has anyone converted to propane with the new FI engines or know of any articles on the subject?

Well, I was at the state fair last summer and saw a EFI 460 that was converted to propane, It may have been a industrial 460 because it was painted blue? Well I know there are kits out to do so because the propane company trucks around here are mid 90's Fords that run on propane.

My dad's 93 F350 is running on Dual fuel, running an Impco 425 mixer with adapter for the dual intake, Model E Vaporisor, and an Autotronics EFI Propane Computer, it works pretty good, easier to switch over than the old carburators

I'm not sure what you are looking for out of your engine in the way of performance, but the simple conversion or addition of dual fuel will drop hp. If you want I can give a few suggestions that you can do to make your friends say " THIS IS ON PROPANE?!!!!!!"

In the 70's Wood brothers ran the #21 car on propane . It was allowed 16 :1 compression is about all I can remember about it other than it didn't take any fuel during the race and they were really fast. I just was wanted to know if the power caught up with gas engines . It should be easier to control fuel ratios now than back in the 70's with the complex computer programs on cars today. I've read that the natural gas companies trucks run on 10.5:1 compression and are more powerful than the gas engines due to 125 octane of natural gas. The fuel storage isn't very big because natrual gas doesn't compress as much as air. Propane still has 110 octane or higher and engine oil changes look like your removing oil with only 500 miles on it. propanes 1.00 a gallon here so money saved isn't enough to make me change over but adding huge amounts of power would.

propane does not have the btu's that gasoline does and nat gas doesn't haver the btu's that propane has. The bottom line is it will cost mpg to go to propane or nat gas. About a 1 mile per gallon. They are significantly cleaner burning fuels than gasoline. Also you are supposed to pay road tax on propane used in cars/trucks which in my area right now puts propane about 40-50 cents a gallon over gasoline. Yes the oil never gets dirty but does wear out so stick to a mileage based change schedule.The basic conversion kits have not changed much over the years. The factory duel fuel is different and more precise but I do not know that you can buy the feature after market.

propane

I have a natural gas well on my property which was a head ache to keep up so I went to propane. Do you know of any new storage systems that doesn't weigh 600 lbs to get 120 miles for natural gas. The last time I checked the local parts store wanted $1800 for it but it had to go on a carberated engine. If I turboed with natrural gas what kind of boost would it take to make 450 hp in a 460. I would like to just build something to try out because nobody else has one more or less. I know if Propane was superior as a fuel the whole world would run on it. Are there any companies building engine specificly for propane or natural gas.
