The 1970 Plymouth AAR ’Cuda was born from Trans-Am racing heritage, but Ken Kelley of Classic Car Liquidators wanted his example to deliver performance far beyond what the factory ever imagined. Underneath its iconic Vitamin C orange paint and vintage AAR graphics lies a thoroughly modernized pro-touring machine engineered to dominate both street and track. Power comes from a supercharged 6.2L Hellcrate HEMI pushing massive torque through a Rockland Standard Gear Magnum Tranzilla T56 six-speed and a Dutchman aluminum rearend with 3.70 gears. Massive Baer 14-inch Extreme Plus brakes with six-piston calipers at all four corners provide the stopping power needed to control this beast, while sticky 315/30R18 tires on 18×11 wheels keep the ’Cuda glued to the pavement.

Speedtech ExtReme Chassis — Bringing the ’Cuda Into the 21st Century

To make the ’Cuda a true modern performer, Ken turned to Speedtech Performance for a complete chassis transformation. A fully engineered ExtReme front subframe paired with a bespoke independent rear suspension delivers cutting-edge handling and torsional rigidity rivaling modern supercars. The ExtReme system integrates JRi coilovers, billet 7075 forged spindles, custom stainless headers, and a dual Borla ProXS exhaust, all designed for maximum grip, precise geometry, and race-ready feedback. Inside, the car blends classic character with modern comfort, featuring a Dakota Digital RTX dash, Vintage Air HVAC, and a premium audio system — making it just as enjoyable on the highway as it is on the track. With its upcoming debut at Ultimate Street Car Association (USCA) events, this reimagined AAR ’Cuda proves what’s possible when you combine vintage Mopar styling with Speedtech engineering: a classic reborn as a modern performance icon.
