Corvette Of The Day: 1963 Superformance Corvette Grand Sport
The original Corvette Grand Sport has a compelling history. In the early 1960s, Zora Arkus-Duntov aimed to create a lightweight, exceptionally fast Corvette with the ultimate goal of winning the GT class at the 24 Hours of Le Mans. The production target was set at 125 units to comply with homologation rules. However, after a pilot run of just 5 cars, General Motors terminated the program and ordered the destruction of the vehicles. Instead, Zora stored two and sold the other three.
Superformance’s 1963 Corvette Grand Sport replica pays homage to that project. It is a recreation of the C2 Corvette Grand Sport, featuring modern technology underneath while preserving the iconic look of the 1960s. Superformance has developed its own platform for this Corvette, incorporating fully independent front and rear suspension, Bilstein dampers, H&R springs, vented disc brakes on all corners, and rack and pinion power steering.
Inside, the car features a touring interior finished in blue leather, an adjustable driver’s seat, carpeted interior and trunk, original style pedals, catches, fittings shifter and hand-brake lever, original style latch and lockbolt sets, sun visors with side and rear view mirror and a heater/defogger as well as the optional power windows and air conditioning which were offered by Superformance as part of the build.
The powerplant buried beneath the hood of this car is what brings the whole package together. While the car already looks fast, the GM Performance Lingenfelter LS3 engine proves that the car IS fast. The engine is rated at 525 horsepower. It features Borla 8-Stack Cross Ram EFI (Electronic Fuel Injection), stock headers and an optional ceramic coated exhaust that end in stainless steel side pipes. The engine is mated to a Tremec T-56 Magnum 6-speed manual transmission.
