Take something old – in this case, a 1933 Ford Roadster body – and make it into something new – a CNG-powered, 600-horsepower beast, perhaps. That's what's happening over at AFVTech, which is prepping the fenderless hot rod for the upcoming Alternative Fuels and Vehicles Institute expo that's coming in May.

AFVTech is using what President Kevin Fern calls the "Natural Drive dedicated EPA-certified CNG retrofit systems" for 600 clean-burning horsepower. The conversion uses a modified General Motors LS7 seven-liter V8 engine (as used in the Chevrolet Corvette Z06), a six-speed transmission, drive-by-wire controls and ABS disc brakes.

The company is also working with the Arizona Fountain Hills High School's research club on turning a 2002 Ford Crown Victoria into a hydrogen-powered vehicle.
