707-HP Hellcat-Powered Pro Touring 1970 Plymouth ‘Cuda

It’s been said that they don’t make them like they did in the good old days, but the good old days didn’t have the 707-horsepower supercharged Gen III Hemi Hellcat engine. When transplanted into a classic Mopar, like this 1970 Plymouth ’Cuda, the good old days are smacked down with a wallop from the fuel-injected future. This thoroughly modern Pro Touring car, with a six-speed transmission and contemporary coilover suspension, offers a seemingly ideal blend of yesterday’s classic style and the incomparable performance capability of today’s technology. It’s a fresh build, according to the selling dealer, with only 529 miles since it was completed.


Under the AAR-style hood is a Hellcat crate engine system, a supercharged 6.2-liter Gen III Hemi V-8 that’s rated at 707 horsepower and 650 neck-tugging lb-ft of torque. It’s used with Chrysler’s control system and front-end accessory drive kit, along with a custom exhaust system featuring long-tube headers and a custom cooling system. The seller reports no issues with the essentially brand-new powertrain, with only 529 miles on it, and no leaks. The engine is complemented with a Tremec six-speed manual transmission and a Dana 60 rear axle.


While the powertrain is thoroughly modern, this ’Cuda’s exterior retains its classic look, with a modified AAR-style hood, painted black and featuring additional late-model-style vents, complementing the contemporary interpretation of the vintage Plum Crazy on the rest of the body. There’s also a prominent rear spoiler and vintage Hemi hockey-stick stripes. The overall effect of blending vintage elements with the contemporary, including a set of 18-inch Boze wheels, appears to be very well integrated. The paintwork is said to be in “show” condition, with no blemishes and no rust, while the other exterior elements, such as the glass and seals, are reported to be in “like new” condition.


Inside, this ’Cuda’s cockpit also appears to mix yesterday and today, with modern gauges set in a stock dashboard and complemented with stock-appearing vinyl bucket seats. The Auto Meter gauges are installed in a custom, carbon fiber-trimmed insert. There are more carbon fiber accents on the classic pistol grip shifter and a Billet Specialties steering wheel. All of the gauges are believed to be functional and all of the interior trim is said to be intact. The late-model Hemi powertrain’s control system is mounted inside the car, below the passenger’s side of the dashboard. The carpet and headliner were reportedly replaced during the build and are said to be in “like new” condition.


The chassis, suspension, and brake systems are reported to have been comprehensively revamped to support the engine transplant and add a more contemporary and responsive driving experience. The upgrades include a Reilly Motorsports front subframe with coilovers and rack-and-pinion steering, along with a Reilly Motorsports Street Lynx rear four-link setup with coilovers. There’s also a Wilwood four-wheel-disc brake system. With only 529 miles on the build, the upgrades are virtually new, with no reported issues or needs. Additionally, the car rolls on 18-inch Boze aluminum wheels, wrapped with Nitto rubber measuring 245/40ZR18 in front and 295/45ZR18 in the rear.


This vehicle will be sold on a clean New Jersey title provided by the selling dealer. Additional documentation for this 1970 Plymouth ’Cuda Pro Touring includes the factory stampings, as well as the fender tag, showing it was originally a 318-powered car. With very few miles since the car was completed, this comprehensively modified Mopar appears to exemplify the very best of the Pro Touring and restomod trends, where vintage style is complemented with modern powertrain and suspension components—and with its “Hellcrate” supercharged engine, it takes performance that was simply unimagined in the good old days.
