Gotta disagree with you, dgc333. Shortly after purchasing my old '69 340 Swinger used in November 1969, it ran 14.28 @ 98+ mph at OCIR. This with just a tuned stock motor, Goodyear Polyglas GT tires (hard), no headers, no SureGrip, and 3.23 gears. And I still have the trophy to prove it.
That's hardly 'could hardly break into the 14's'.
I'm currently building my "new" '69 Dart with a 380hp 360 crate motor with a few additional goodies and looking for much better performance with a well-balanced overall package.
