I don't know why i like the odd stuff. i have a 82 f250 HD that had an in line 6 until cheap gas destroyed all 6 pistons. it was a great farm truck and beat up enough to show no fear of scratches. while in a military junk yard this weekend i found several industrial 6 cylinders ford engines. several were lp fueled, which had pretty good prices. my gas carb will bolt on, but some of the guys i work with say to leave it lp. any one out there with experience on lp fueled trucks? Thanks

I have a LP MMGVI that runs like a top also you
can run off of vapor for economy or liquid for power.Economy
propane in Gordonsville VA has several used tanks for sale that would work in the back of a pickup

When a kid I rebuilt an engine on a Ford 8N tractor that run on propane. The pistons and cylinder walls were clean as a whistle except for a thin white powder. There was no gunk at all in the oil pan. Power on that tractor was not sufficient to pull a two bottom plow, but was enough for light pulling and running a hay rake. Never had any problem with it starting except on zero degree mornings. Cost of operation was cheaper than with our other 8N that run on gasoline.

That's right. I've seen our local propane co with over 300,000 miles on delivery trucks and still going til the body and chassis falls down. They use Chibby 3/4 ton with 350 engines to deliver and set up tanks.

When these fellers buy their old trucks for the engines to go in a farm truck there is no sludge in them.

I could not believe it but there was just a very slight film down under the intake manifold when they pulled it to put a carb on the engine.

We looked in the oil pan and there was almost no wear on the bearings and absolutely no oil sludge built up.

If I could keep it propane I would use propane and leave the carb off of the salvaged engines.

RH- Suggest you grab them surplus bargains!

LP has about 66% of the BTU of gasoline. It is a super high octane fuel, with superb anti-knock properties. Your post sounds like your old engine died because of low octane fuel...

LP engines have the spl valves and seats and high compression pistons. Run on on gasoline under load and it'll blow in a short time.

A big problem with LP is that each batch had a different BTU and the farm tractor driver was all the time fiddling with the mixture screw. Another was that people couldn't comprehend the 66% BTU when it was compared to gasoline MPG over the road.

For energy content comparison purposes-
Gasoline = 100%
Diesel = 125%
Propane = 66%
Ethanol = 66%
Methane = 50%
Methanol = 50%
Flatulance = 45%

Gasoline and diesel are low octane, but all the rest work great at 12:1 or higher CR.

Like the old bumper sticker sez, "Eat more beans, Iowa needs gas!" Grins, IHank

Talk to your local LP supplyer, most LP companys run their trucks on LP.
