The **1970 Plymouth Barracuda Gran Coupe Hemi** you see here is far from stock. It represents a serious commitment to muscle car performance and quality restoration. This particular example underwent an extensive refurbishment that started around 2010. The core of this transformation involves a powerful Keith Black aluminum 426ci Hemi V8. Although the car sustained accident damage in the past, a skilled owner brought it back. This resulted in a highly modified and visually striking E-body coupe.
Restoring the Gran Coupe to Glory
Following its acquisition in 2012, the seller meticulously addressed prior accident damage. The right-side door and quarter panels were expertly repaired. Then, the car received a fresh coat of Deep Burnt Orange Metallic paint. Numerous exterior pieces were replaced during the refurbishment process. This includes the chrome bumpers and front and rear glass. Furthermore, the grille, fog lights, and various trim pieces are new. The car retains key muscle features like the classic Shaker hood. Black Hemi “hockey-stick” graphics run along the sides. A satin-black rear wing adds an aggressive look.
A Blend of Classic Style and Modern Upgrades
The exterior balances period-correct design with performance cues. Argent-colored finishes are seen on the grille and rocker-panel moldings. A satin-black tail panel provides visual contrast. Other features include fender-mounted turn-signal monitors and tinted glass. Dual exhaust outlets exit cleanly through the rear valance. The three-speed windshield-wiper motor was also carefully rebuilt. New window felts and door weatherstripping ensure a tight seal. Overall, the car presents as a high-quality, rebuilt machine.
Upgraded Suspension for Enhanced Handling
Underneath this Mopar icon lies a completely overhauled suspension system. The front suspension features QA1 lower control arms and modern torsion bars. Calvert Racing CalTracs traction bars are fitted at the rear. These are combined with heavy-duty leaf springs and KYB shocks. This setup ensures excellent traction and stability under power. The front crossmember and other suspension components received a powder-coating treatment. Furthermore, the power steering system was completely refreshed. This included rebuilding and revalving the pump. A new steering gear from RedHead Steering Gears was installed recently in 2024.
Stopping Power and Rallye Wheels
The car sits on handsome Rallye-style 17-inch aluminum wheels. These wheels were sourced from YearOne. They are wrapped in high-performance BFGoodrich g-Force Comp-2 tires. Stopping duties are handled by power-assisted vented discs at all four corners. A Wilwood master cylinder manages the brake fluid flow. A proportioning valve and stainless-steel lines augment the system. The four-wheel disc setup provides greatly improved braking performance over stock.
Inside the Revamped Barracuda Cabin
The interior received a comprehensive overhaul during the recent refurbishment. Both the front bucket seats and the rear bench were rebuilt. They were then retrimmed in classic black vinyl. Before installation, Kilmat insulation was applied for noise reduction. This makes the cabin quieter and more comfortable. The carpeting, seat tracks, headliner, and dashboard were all replaced. Interior appointments include a woodgrain-trimmed center console. The car features ‘Cuda-branded carpeted floor mats. A modern Kenwood stereo and a functional cabin heater are also installed.
The Driver’s View and Drivetrain Overhaul
A woodgrain-rimmed steering wheel frames the classic gauge cluster. It includes a 120-mph speedometer and auxiliary gauges. The auxiliary gauges monitor fuel level and coolant temperature. They also show the alternator’s status. The five-digit odometer shows 200 miles since the rebuild. The steering column was also rebuilt under the current ownership. Power from the Hemi V8 is routed through a rebuilt TorqueFlite 727 three-speed automatic transmission. A high-stall torque converter was installed. The stout Dana 60 rear end was also completely rebuilt. The driveline and yoke were replaced to handle the immense power.
The Keith Black Aluminum 426 Hemi Engine
The engine is the undisputed highlight of this build. It is an aluminum 426ci Hemi V8 supplied by Keith Black Racing Engines. The seller’s shop reinstalled this unit in 2023. This powerful engine breathes through dual Holley 750-cfm carburetors. It utilizes an electric fuel pump for consistent delivery. MSD ignition components and a high-torque starter aid in reliable operation. A four-core copper radiator keeps temperatures in check. Ceramic-coated headers feed into a full aluminized exhaust system with Flowmaster mufflers. This setup provides serious power and an aggressive sound.
Power, Engine Specs, and Performance
The centerpiece is the aluminum-block 426 cubic inch Hemi V8. This engine configuration is famous for its colossal torque and top-end power. While exact figures depend on the tune, a built Keith Black Hemi V8 of this size easily produces over 500 horsepower. Paired with the three-speed TorqueFlite 727, power delivery is immediate and brutal. The upgraded suspension, including CalTracs, ensures this power translates to straight-line speed. It is a genuine high-performance muscle car that commands respect. This **1970 Plymouth Barracuda Gran Coupe Hemi** offers exhilarating acceleration.
