1969 torino cobra - 428 cobra jet, heads bored 60over, 3spd auto, 3 deuces, headers, some major weight reduction. It was really loud, and really fast, rebuilt specifically for drag racing. I miss it quite a bit, but needed too much work. Wasnt really suppose to be driven on the street.
As far as a street car, the fastest I have owned is my 1982 928
