Featured a 383 engine and had two hood scoops, which could be substituted with a “shaker” scoop, so called because of its vibrating motion when the car was moving.it featured a Six-Pack version of the 340 5.6-liter engine with a humongous hood scoop, dual exhausts in front of the rear tires, sway bars, heavy-duty suspension, and the innovative different-sized wheels in front and back. A rear ducktail spoiler and three striping options (rear, side or none at all) enhanced the race car image. It got about 350 bhp and made a quarter-mile in 14 seconds. This SIX PACK Challenger R/T did come factory equipped with the Rallye Gauge Dash, Console, Pistol Grip Shifter, Power Steering, and Power Brakes. So, no matter how you cut it, this is one well-appointed R/T. The overall effect is a factory appearing.Challenger’s SE package added a vinyl top with a smaller rear window. The Gran Coupe model added body sill, wheel lip, and beltline moldings. The paint is looking great in the photographs and video, but the owner is transparent when mentioning that it isn’t perfect.
