At the heart of Doughboy is an ACE Racing Engines-built 540 cubic-inch Brodix big block with forced induction from twin Precision 8385 Next Gen turbos. Custom 3D-printed carbon-fiber radiator ducts and heat exchanger outlets are incorporated into the air-to-water intercooler system. The in-house engineered intercooler system not only supports performance but also serves as the front core support for the grille while maintaining the original “V” shape of the Chevelle. The engine has been shifted back 15 inches, improving chassis balance for optimized handling on track. It’s equipped with dual 10-GPM Aeromotive Brushless fuel pumps in a rear-mounted custom billet fuel cell that doubles as a rear diffuser to improve aerodynamics.

The team has meticulously designed and manufactured every part of the engine bay, from the custom billet intake with integrated dual-purpose fuel rails to the billet valve covers designed to clear high-lift Crower roller rocker arms. The CAD-designed firewall was formed utilizing a new CNC technology to ensure a precise and high-quality surface finish, a technique unseen in most builds.

Doughboy sits on a heavily modified Art Morrison Enterprises chassis with Corvette C7 independent front suspension geometry, strengthened to support the massive power output. The fully custom front and rear suspension is made with a five-axis CNC unit using billet 7075-T6 aluminum and utilizes spherical uniball joints and rod ends for precise control and adjustability. JRI hydraulic coilovers allow for on-the-fly fine-tuning, enhancing the car’s ability to adapt to different driving conditions on both the street and track.

Wilwood SX6R six-piston brake calipers finished in 24-karat gold provide stopping power. Kompression Wheels' custom 20x13 front and 20x15 rear billet three-piece wheels are wrapped in Michelin Sport Cup 2 tires in 325/25R20 and 345/25R20, respectively.

Doughboy’s widebody is hand-sculpted and 3D-scanned for precise fitment and finished with Porsche’s factory Night Blue Metallic paint. Inspired by modern GT Cup cars, the body maintains the classic muscle car aesthetic of the 1970 Chevelle while incorporating contemporary elements like cleanly integrated side-exit exhausts, a carbon-fiber flat bottom and a custom 3D-printed front bumper with integrated air ducts. The rear of the vehicle features a carbon-fiber trunk lid with integrated cameras acting as turn signal indicators, further emphasizing Doughboy’s blend of vintage design with modern technology. Custom infinity taillights and shaved drip rails round out the exterior’s modern aesthetic.

Inside, Doughboy continues its fusion of form and function. The roll cage, crafted from 4130 chromoly tubing, is designed using CAD and CNC processes, while billet aluminum A and B pillars give it an exotic and race-inspired touch. A Motec C1812 display unit is integrated into the dash above a custom tilt steering column mated to an Audi R8 steering wheel, which allows quick access to all driving controls, including the paddle shifters and the ability to switch tuning maps on the fly. Crafted by Avant-Garde Design, the interior balances ruggedness with luxury, ensuring Doughboy is as comfortable as it is capable. The car also features a top-tier sound system to rival any high-end aftermarket setup, ensuring no detail was overlooked.

Finally, the engine management system is a Motec 150 powered by two Motec PDM 30 units, allowing the entire 16-volt system to work without using a single fuse or relay. Utilizing Deutsch Autosport connectors, the system is married by a mil-spec motorsports-grade wiring harness sealed front to back. Lifeline’s 360 Fire Suppression System manages safety for the interior, engine bay and fuel system.
