I had a 6 speed manual Cobra Mustang with Kenne Belle supercharger, boy did it spoil me with the highway RPM's. But I sold it and bought my Duster project, once the Mopar bug is in you there's nothing that compares. But I do want to hit some distant car shows without buzzing the motor the whole way. As soon as you go to a track you want them 4.56 gears!
