This is my 81 W150, 4 speed, slant six. Runs on propane, 10.5:1 CR, my own cam specs, crank trigger ignition timed by a Megajolt and lots of future mods, including winches, extra battery, 90a alternator, lift, lockers at both ends, 4.11 gears and 32 inch tires. It's an adventure / offroad / work / rescue truck.

I always liked the PowerWagon that was on the Simon and Simon TV show back in the mid-80's.

There's no such thing as too much cam....only not enough engine!

That is a sharp truck, and with that trans and axle gearing you can pretty much pull anything you wanted.

How is the propane system for daily use, any mileage figures?
