I have about 75 passes on this car, a very high option 71 Charger R/T .I put on some drag radials, drive 80+ miles, pul it to the line and it runs high 12s all day long. I did build the motor with some racing in mind but it wins at the car shows too. I also have a 71 Challenger 440/6pk that will be at the track this summer, a numbers match sixpack shaker car in the very rare Citron yellow.
