'71 Dodge Challenger Convertible
Built by XV Motorsports
Irvington, NY

Mopar Power

  • Engine: A 6.1-liter, 372ci Hemi, balanced/blueprinted, hand-assembled, and loaded with parts made by XV Motorsports, which includes all the stuff you didn't get for Christmas: XV's own single-plane intake with billet throttle body, fully ported/polished heads, performance camshaft, equal length headers, 3-inch stainless steel exhausts with H-pipe and stainless Magnaflow mufflers, and a custom-tuned engine management system good for 600 hp.
  • Transmission: Viper-spec T-56 six-speed (with triple-cone synchros for proper high-rpm shifting), with dual-disc hydraulic clutch and pistol-grip shifter handle.
  • Rearend: 8-3/4-inch rearend, with 4.33:1 rear gears that work great with the T-56's overdrive fifth and sixth gears.
  • Sure Grip

  • Suspension: XV Motorsports' Level II suspension system replaced OEM torsion bar/leaf setup with a short/long arm, double A-arms/high-pressure aluminum monotube coilover front suspension, a three-link with aluminum monotube coilovers, and Panhard rod in back. One more thing: Custom-fabbed antiroll bars. Two more things: Custom aluminum front spindles.
  • Brakes: If just enough (i.e., stock Mopar brakes) are good, a lot more is even better. The 14-inch rotors and six-piston calipers stop the front, while 13-inch rotors and dual-piston calipers are on duty in back.
  • Wheels: Now, these are "New York Giants!" wheels are forged three-piece Kinesis rims, 18x9-1/2 inches in front; 18x12s in back.
  • Tires: Michelin Pilot Sports, 275/35YR18 in front, 335/30YR18 in back.
  • High Impact

  • Body: A rare one (one of less than 2,200 '71 Challenger convertibles built) treated to remedial metalwork and paint prep by XV Motorsports. They also added structural reinforcements to keep the roofless steel body from pretzelizing when the go-pedal is mashed to the floor. Body features include a Shaker hood and billet/hydraulic hood hinges.
  • Paint: Bright blue, sprayed on by XV Motorsports. Remedial bodywork and paint preparation also done by XV Motorsports.
  • Interior: Recaro bucket seats flank an XV-made console that houses an Alpine sound system, Pistol-Grip shifter, and dual cupholders. XV also did the custom steering wheel. the custom gauge set includes a 200-mph speedometer and 10,000-rpm tach. Seats and side panels upholstered in leather complement the Challenger's body color.
