mult fuel ?

I have a 99 dodge ram 1500 with the 318 and auto.
I know i can convert it to run on LP gas, anyone know of a kit that will allow run LP gas and/or GAS??
At 1.75 gl for Lp would sure cut down on costs. and beining able to run reg GAS would help for towing.
anyone thanks

You may want to rethink the idea for the following: Propane = 91,000 BTUs Gasoline = 125,000 BTUs So by using propane you have reduced the efficiency of internal combustion by 27% or 34,000 BTUs.
Propane or LNG will reduce your engines HP on an average of 40% because of the thermodynamics in the combustion process and reduced BTUs.
So if you got 15 MPG you will now get around 6 MPG.
So if you had a 20 gallon tank with gas you could travel 300 miles.
With a propane fuel system 20 gallons will get 120 miles per tank.
The difference of 180 miles so you would fill up your tank 2.5 times more than gasoline
2.5 x $ 1.75 = $4.38 In reality at $3.00 a gallon for gas you would end up spending $1.38 more per gallon.
If you do it yourself the propane conversion costs would be about $2400.00
So what appears to be a savings is not just smoke and mirrors

You are way off on most of this. While it is true that propane has less energy than gas, (20 to 30% depending on whether gas is E10 or pure and more energy than E85) you will simply pure more to get the same heat input. Propane is a excellant motor fuel and burns cleaner than gas (cleaner than natural gas in a motor too) and with some kits it actuallys make more power on propane. Proapane has a little different burning curve and requires a bit more spark advance than gas to do its best and engines that do poorly with it are not properly timed. (like if they are tuned for low octane fuel) Also propane has a very high octane (110+) so if you want to you can raise compression to 12 to 1 or higher with no fear of knock even towing and in the process get even more power and MPG. If you get sav 15 MPG on gas, you should get about 11 to 12 on propane in a stock engine that is properly timed and it you mod the engine to higher compression to take advantage of propanes octane, you will get near the same MPG as you did with gas on a stock engine because of improved thremodynamic efficency. WHile it is also true that you have to install a heavier fuel tank to hold propane, it only weighs 4lbs/gal vs 6.5lbs/gal for gas which offsets the weaight of tank and there is not problem towing with propane other than finding it for fuel. ----------------- The SnoMan www.thesnoman.com

I ran a fleet of converted gas engines to propane in the 70s and mileage was poor along with power. A 360 engine would only deliver 145 HP from it's 280HP after conversion. You can help as you said by raising the compression however BTUs do not lie and there is a big difference between propane and gasoline.
The conversion was done at the factory by the manufacturer and it did not matter if it was a Chevy, ford or dodge they were poor. The only good thing we could get 300k out of an engine and when torn down it was whistle clean unlike gas engines. At that time we were getting 5K between oil changes.

You can a very poor conversion because like I said it cam make just as much power or more IF done correctly. Check out link below and I have another one when I find it that covers conversions to GM 8.1 in med duty trucks and they make more HP and torque on propane than gas after dual fuel conversion. People do bad conversion and then blame the fuel when it is the method that is bad.

We have either propane or LNG crown vics at work, police package I believe. They run pretty damn good.

LP is a GAS
