5.4 Dimensions
I have two possible candidates. A 1972 Gran Torino Sport, full frame car so no shock towers. A 1963 Fairlane, with Mustang II front suspension, so again no shock towers. Torino weighs about 4,000lbs., and the Fairlane is about 3200. Either should be quick with a Lightning engine, and probably 20+ MPG. Should be different anyway.
