Streamline Custom Designs has built a gorgeous 1973 Challenger resto-mod. It first appeared at the 2021 SEMA show and is now being auctioned off by Barrett-Jackson during its Scottsdale auction running from January 22-30. The power comes courtesy of a 6.4-liter HEMI V8 with a Magnuson supercharger that’s paired to a Paramount 45RFE automatic transmission. A custom exhaust system was also manufactured for the car and includes MagnaFlow mufflers. Elsewhere, Streamline Custom Designs has equipped the Challenger with a Ford 9-inch rear end, QA1 adjustable coilovers at all four corners, and potent Wilwood brakes both front and rear. Underpinning the car is a custom tube chassis that incorporates a roll cage. New body panels have been fitted, including a revised front bumper, grille, and headlight surrounds, as well as a distinctive rear bumper. The muscle car also features a bespoke hood with air intakes. All exterior parts are bathed in PPH Envirobase Streamline Slate Grey. It also sports Schott center-locking wheels measuring 19×9 at the front and 20×12 at the rear. Finally, the interior has also been comprehensively updated and is upholstered in black leather with suede inserts and a headliner that neatly hides the roll cage. For entertainment, it has a 2000-watt Kicker stereo system with two 10-inch subwoofers.
