"Back in the Day" (1968) we had a 1963 Dodge 4 door that was a county squad car in another life. It had a 383 with 440 head and intakes and a 4 barrel carb (ordered from the factory that way) that would kick just about anything around without doing anything to it. This was a smaller, lighter car than comparable cars later on in the late sixties and early seventies. I drove another ex squad car set up the same way, only it was a '66, and it was an absolute dog compared to the '63.
No one lives forever, the trick is creating something that will.
