This is a 1967 GT Dart. When I bought this car, it was being used as a quarter mile race car, with a 440 in it. I got the original 273 engine and 4-speed and reinstalled them. I kept the posi rear end with 4:30:1 gears. Wow! No top end, but man was it fast off the line! I sold this car to Tom Collins of Big Sky Mopar in Montana.
