Orange Crush
Hailing from West Warwick, Rhode Island, were Scott and Wendy Dickinson and their understated-looking '73 Challenger. At first glance, Scott's Challenger looked like the epitome of a "sleeper," but once he opened the hood that thought was quickly removed from our minds.

Fourteen years ago, Scott was looking for a Barracuda, but he found this car sitting along the side of the road and decided that it would fill his needs just fine. Since Scott owns SD Concepts Engineering, it's no wonder the car runs like it does.

Under the hood is a very large ATI supercharger mounted on the usually overlooked 383. That's right, we said a 383. Scott's philosophy is the 383 is as good as any other Mopar engine, and we think he proves his point very well. this car has been running 8-second quarter-mile times for seven years now on the same engine and blower. Scott tells us that, on average, he and Wendy put 1,000 to 1,500 miles on it driving it on the street.
