D Dart spec. Anyone build one?

I had a 3.55 7.25 SG survive 6 months behind a 68 spec 340 with 10" wide tires and a 727 in a lightweight 65 A. The only way I killed it was doing a neutral drop rolling backwards out of a driveway. I think it would still be working if I didn't pull that bonehead move. That '65 was pretty quick. I regularly toyed with a neighbors stock looking 340 Duster and always took it off the line.
