I have a 47 Dodge 1 ton flatbed that I have had for 40 years. I bought it originally for the wheels, but decided to build it. I originally put a 383 Dodge in it, for about 15 years, then replaced it 17 years later with a 440. I am currently rebuilding it for the 3rd time. I've installed a Mustang front end and a rear end clip from a Ford Expedition (IRS and disk brakes), and a NP 4speed, I am currently rebuilding a Dodge 440 to replace the wore out previous engine.
