Mopar Power
Engine: A Mopar Performance crate engine (P5153474) that has been bored .020-inch over based on a production 5.9 Magnum block. Oiling is controlled by a stock high-volume pump and an 8-quart center-sump street/strip oil pan. A 4-inch stroke Scat cast-steel crankshaft drives a set of Mopar 6.123-inch forged rods and cast hypereutectic pistons. The valves are actuated by 1.6 Mopar rocker arms and a 230/234-duration, .501/.513-inch lift hydraulic roller camshaft. The rockers rest atop heavy-duty Mopar valvesprings, which take the beating of the aggressive cam that is controlled by a double-roller timing chain. Air and fuel are brought into the small-block via a 750-cfm Holley carburetor and an aluminum M1 four-barrel intake manifold. The mixture is brought through the cast-iron Magnum R/T cylinder heads and ignited by the Mopar Performance electronic ignition. It's then exhausted through tti 15/8-inch stepped headers and a 2.5-inch tti exhaust. After Lance Patton's tuning, it's rated at 435 hp and 470 lb-ft of torque at the flywheel.
Transmission: An electronic overdrive 4L60E was built by Bowler Transmissions and adapted to the Chrysler bolt pattern. It's controlled by a stand-alone HGM controller. The 2,300-rpm stall torque converter features an 11-inch lockup clutch and 9-inch cover. A driveshaft from Ron's Driveline of Gainsville, Georgia, sends the power to the rear.
Rearend: The stock 8 3/4 is packed with Moser axles, 3.55 gears, and a rebuilt factory Sure Grip.

Sure Grip
Suspension: (Front) Magnum Force tubular upper-control arms take the place of the factory units, while Mopar Performance torsion bars set the ride height. A set of KYB shocks and an Addco 1 1/8-inch sway bar make the Duster feel like it's on rails. The front end was also treated to a PST polygraphite suspension kit to round off the front end. (Rear) Eaton Detroit springs give the Duster a 1-inch drop, while rear KYB shocks dampen the road bumps. A 7/8-inch Addco sway bar keeps the rearend stable during cornering, and Magnum Force subframe connectors prevent the chassis from twisting.
Steering: A Steer & Gear rebuilt steering box.
Brakes: SSBC Tri-Power three-piston front calipers grab massive 13-inch slotted rotors. The SSBC package required the use of '73 A-Body spindles; YearOne adapted the hydroboost system. Single-piston SSBC calipers and 12-inch rotors slow down the rear.
Wheels & Tires: Chip Foose-designed Nitrous II wheels, measuring 18x8-inch in front and 19x10-inch in the rear, sport BFG G-Force T/A tires. They are sized at 225/40-18 and 285/35-19, respectively.

High Impact
Body: The original body was in excellent shape so not much work was done on it. It received a new windshield and back glass, but retained the OE side glass.
Paint: Ted Moser of Motion Picture Warehouse painted the car Dark Graphite on top and Saab Frost Green Metallic on the lower half. The hood treatment was designed by Chip Foose.
Interior: YearOne replaced the carpeting, rear seat covers, door panels, package tray, and headliner. Just Dashes restored the dashpad, and Cerullo front bucket seats were covered in leather that matched the YearOne design. Henderson's Upholstery in Gainesville, Georgia, handled the front and rear seat covering.Kicker Audio designed a center console that simulates the original console's shape. The modern audio system features an Eclipse CD/DVD player and a slew of Kicker speakers, tweeters, and subwoofers. They also crafted the trunk enclosure that incorporated the amplifiers, vents, and spare tire. The factory mono-speaker AM/FM radio still works.
