The 1970 Plymouth Road Runner remains a quintessential symbol of the muscle car era, yet this specific example redefines the breed through modern engineering. Previewed at SEMA 2011, the car underwent a comprehensive nut-and-bolt custom build that prioritized performance and aesthetics. It stands as a sophisticated restomod, blending vintage Mopar lines with late-model Hemi power. The striking PPG Candy Apple Red exterior ensures it captures attention from every angle. It will cross the block as a premier lot during the Glendale 2026 auction this March.
Advanced Hemi Engineering and Injection
Modern reliability meets classic displacement under the power-operated air grabber hood scoop. The heart of this 1970 Plymouth Road Runner is a 6.1L Hemi V-8 engine, a significant departure from original big blocks. It features an Imagine Injection stacked intake system with individual throttle bodies for a dramatic visual and performance boost. A Fuel Air Spark Technology management system handles the engine electronics with precision. Additionally, a billet aluminum serpentine belt system ensures all accessories run efficiently during high-speed operation.
Chassis and Suspension Innovations
Handling a modern Hemi requires a chassis that can manage the torque and weight effectively. This build utilizes an RMS AlterKtion front suspension paired with a Street-Lynx rear setup. Front and rear coilovers allow for a fully adjustable ride height and improved cornering stability. The frame is further strengthened by Hotchkis subframe connectors and custom rear torque bars for added rigidity. Consequently, the car provides a level of road feedback and control that surpasses original factory configurations.
Interior Craftsmanship and Modern Comfort
The cabin offers a stark contrast to the aggressive exterior with its custom Tan leather interior. A fiberglass dashboard houses custom gauges that provide clear, accurate readouts for the driver. Power-operated seats ensure the perfect driving position, while air conditioning keeps the interior cool during summer cruises. Modern conveniences like power locks, windows, and a custom audio system make the car a viable long-distance tourer. A billet aluminum tilt steering column and leather-wrapped wheel complete the high-end workspace.
Braking Power and Exterior Finishing
Stopping this high-performance machine is handled by a set of Wilwood drilled and slotted front disc brakes. These performance stoppers are visible behind the spokes of polished Foose wheels, which enhance the car’s pro-touring stance. The PPG Candy Apple Red paint is applied over meticulously straightened metal for a deep, liquid-like finish. Furthermore, billet hood hinges and stainless steel lines showcase the attention to detail throughout the engine bay. Every component was chosen to balance show-quality beauty with real-world functionality.
Performance Specifications and Drivetrain
This 1970 Plymouth Road Runner produces impressive power from its fuel-injected 6.1L Hemi V-8. The engine is mated to a GM 4L65E 4-speed automatic transmission for smooth and reliable shifting. A limited-slip differential helps transfer power to the pavement effectively during hard acceleration. Rack and pinion steering replaces the original gearbox for much more precise directional control. These technical specifications transform the muscle car into a modern grand tourer capable of modern traffic speeds.
Summary of the Road Runner Custom
This 1970 Plymouth Road Runner is a masterpiece of modern fabrication and vintage style. Its history as a SEMA vehicle confirms its status as an elite-level build. The combination of Hemi power and advanced RMS suspension makes it a thrill to drive on any road. It avoids the compromises of original muscle cars while keeping the spirit of the Road Runner alive. Collectors looking for a turnkey custom with serious presence will find this car hard to overlook. It remains a definitive statement in the world of high-end restomods.
