That'll work if you don't need "Air Care".
Propane is a good option at $0.45 a liter. My F350 with a propaned 460 is cheaper to drive than my mini van.

It works great, get a used set out of the buy & sell, usually around $400.00
Only get the 425 cfm Impco system, & spent the money on a new base plate.
Only draw back with the Fords are that the rear under body tanks are only 120L. I had a '79 with a tank under the cab, but it hung low. My F350 has the tank under the rear & a double stacker in the front of the box. With this setup, I only lost 16" of the front of the box.

Some guys will tell you that you'll have problems in cold weather, you won't if you install the vapourizer properly. It must be mounted lower than the top of the water level in the radiator. I always mount them as low as I can on the wheel well. If you vapourizer isn't completely full of coolant, it will freeze up even in the middle of summer.

propane is the good stuff, 104 octane. You can run 10-11:1 compression on a halfass tune...with tweaked in tuning like 12.5:1 is doable. Most ppl say 10:1 is good tho. Check out http://fuelsforum.rasoenterprises.com/ and go to their propane section.
