    I ran up on gotpropane.com and am pretty impressed with the looks of the products they sell. I was considering perhaps converting my 350 to propane years down the road (when I get rich.) It just looks kinda interesting to me. I was wondering if any of yall run propane as your primary fuel and what you though about it. How does it affect horsepower/economy? what are the pro's and con's?

    I've never heard of propane being the sole fuel for a gas motor.... propane itself is less powerful than gas. When you add a little propane into diesel or gas it somehow bumps power. Thats about as far as my propane knowledge goes.

    I wouldnt do it if its your DD. You would have to have a HUGE tank to be able to go any miles with it. Propane is a higher octane fuel then gas. The componets to go to propane are only about $400.

    it's not my Daily driver. would my motor have to be internally modified to compensate for the slower burning fuel? where can you get the components for $400 (they are like $1000 at gotpropane)? I wish I knew how it would compare economically to running regular gas.

    Converting to propane is not worth the hassle anymore. Propane prices have gone up faster than gasoline prices. At one time propane was little more than half the price of gasoline, but after gasoline prices started skyrocketing in late 2001, the energy companies did not want a wholesale propane retrofit movement to begin, so they jack up the price of propane to about almost as much as gasoline.

    Right now propane is only about 10 cents a gallon cheaper than gasoline. It would take decades of driving to get your Return on Investment (ROI) anymore. There is about a 20% horsepower loss with running propane as compared to gasoline. You can make up for that 20% loss by increasing compression, and installing a camshaft with lots of duration. Since propane is a high-octane fuel, it likes high compression. You can also get special camshafts for propane engines as well because propane likes lots of valve timing overlap.

    what is the highest compression you can run with propane?

    seems like an alternative diesel.

    Propane has a prospective octane rating of about 114, so the sky is the limit. 14:1 would likely be no problem with propane.

    Propane

    August 2005 issue of Off-Road magazine has an interesting article about the propane conversion. Seems to be mostly positive, but, what mag article isn't?
