1963 Corvette Grand Sport Superformance Lingenfelter Performance Engineering

The original 1963 Corvette Grand Sport was built to hunt Shelby Cobras before GM’s corporate ban on factory racing killed the program after just five cars. This continuation, built by Superformance under official license from General Motors, uses molds derived from the original factory tooling and a tube chassis matching the originals. This particular example pairs that pedigree with a Lingenfelter LS7, four-wheel vented Wilwood brakes, and enough creature comforts – A/C, power windows – to make it as livable as it is fast.

In 1963, General Motors built five Corvettes that were never supposed to exist. Corporate leadership had signed onto an industry-wide agreement to stay out of factory racing, and Chevrolet’s Grand Sport program – a lightweight, tube-framed weapon built to hunt Shelby Cobras – died almost as soon as it started. Six decades later, a car wearing that same name and profile is back on the market, built not in secrecy but under official license from General Motors itself. This one carries a Lingenfelter LS7, four-wheel vented Wilwood discs, and enough tube-frame pedigree to make the original engineers nod in approval. The only thing missing is the ban that killed the first five.

The Racer GM Was Not Supposed to Build

Chevrolet’s original Grand Sport program produced just five lightweight, tube-framed Corvettes intended to go after Shelby’s Cobras on the track, before GM corporate leadership shut the program down under the industry’s anti-racing stance. The handful of cars that escaped before cancellation became some of the most valuable and mythologized Corvettes ever built.

A Continuation Built From the Original Molds

Superformance builds its Grand Sport continuation under official license from General Motors, using a tube chassis engineered as an exact continuation of the five originals. The fiberglass body is hand-laid using enhanced molds derived from the original factory tooling. Buyers can choose from a supercharged 6.2-liter LS9 making 635 horsepower, a 6.2-liter LT4 making 650 horsepower, or a period-style 377-cubic-inch small-block replica, paired with a Tremec six-speed manual and a fully independent suspension riding on Bilstein dampers and H&R springs.

This particular example builds on that foundation with a Lingenfelter LS7, a tube frame, and four-wheel vented Wilwood disc brakes, plus creature comforts like air conditioning and power windows – a street-legal race car built for someone who wants Grand Sport pedigree without giving up daily comfort.
