SEMA-Built 1963 Corvette Resto Mod Set For Mecum Auction

638-hp 1963 Corvette Resto Mod brings modern ZR1 power to a classic icon

Set to cross the auction block at Mecum Auctions on September 26, this 1963 Chevrolet Corvette Resto Mod represents a compelling fusion of one of America’s most recognizable classic designs with the formidable performance technology of a modern supercar. Built by Legacy Innovations, LLC of York, Pennsylvania, the project preserves the visual character of the legendary split-window Corvette while extensively reengineering its mechanical foundation.

The centerpiece is a supercharged 6.2-liter LS9 V8 sourced from the C6-generation Corvette ZR1, producing a factory-rated 638 horsepower. Power is delivered through a Tremec T-56 “Tranzilla” six-speed manual transmission, complemented by custom stainless-steel headers and side-exit exhaust pipes that reinforce the car’s aggressive character.

Beneath the period-inspired bodywork, Legacy Innovations installed a TIG-welded tubular chassis, Detroit Speed rack-and-pinion steering, and a Detroit Speed Quadralink independent-style rear suspension arrangement. A Ford 9-inch rear end incorporates a Strange S-Trac aluminum Positraction differential with a 3.73:1 final-drive ratio. Stopping power comes from Wilwood four-wheel disc brakes with engraved calipers, while Mickey Thompson SR Radial tires are mounted on Billet Specialties beadlock-style wheels finished with 1063-style knock-off cones and spinners.

The build also incorporates substantial carbon-fiber and bespoke detailing. A custom reverse-opening carbon-fiber hood complements the extensively upgraded chassis, while the cabin features custom leather upholstery with 1967-style headrests. Modern conveniences include air conditioning, power windows, remote-operated power locks and a concealed custom stereo system.

Having debuted at the SEMA Show, the Corvette reportedly represents an investment exceeding $300,000. More than a conventional restoration, it is a purpose-built interpretation of the C2 Corvette—combining the visual purity and cultural significance of the 1963 split-window with the brutal acceleration and engineering sophistication of Chevrolet’s supercharged ZR1 powertrain.
