I have a Holley 4bbl 4180 w/ a Century propane carb sitting on top of it. Its a dual fuel setup. Its on an 1986 F-250 460.
I've got an '83 F250 with a 460 in it. I'm very interested in a similar combo for my truck... can you tell us more about your propane conversion, such as where you had it done, approx. cost, has it been trouble-free, what's the power and mileage like, and any other comments you'd like to add?
