The 1963 Chevrolet Corvette Z06/N03 represents the absolute zenith of early Sting Ray production and mid-century American racing ambition. Developed specifically for SCCA competition, the Z06 package transformed the stylish split-window coupe into a factory-built endurance racer. This Daytona Blue example is one of only 199 Z06 Corvettes produced for the model year. More significantly, it features the ultra-rare N03 36-gallon “Big Tank” fuel system, making it one of just 63 such units. Experts believe this car is one of only five surviving N03 tankers to still retain its original factory engine. Its provenance is further elevated by decades of ownership under former NCRS Director Mike McCagh. Having earned the prestigious NCRS Top Flight award, this Corvette is recognized for its historical accuracy and condition. It will cross the auction block at Kissimmee 2026 as Lot F233. For the serious collector, this Z06 is not just a car but a blue-chip historical artifact. It stands as a definitive bookend to the short-lived but legendary era of the factory-competition split-window.
Daytona Blue Styling and Competition Chassis Details
The exterior of this 1963 Chevrolet Corvette Z06/N03 is finished in the deep, sophisticated shade of Daytona Blue. This hue perfectly complements the unique one-year-only split-window roof design that has become a global automotive icon. Because it was built for the track, it sits on a specialized heavy-duty suspension with unique shocks and springs. It also features a larger front sway bar and a dual-circuit master cylinder for improved safety under duress. The wheels are currently fitted with period-correct blue stripe tires that highlight the car’s racing heritage. Additionally, the sale includes the original factory hubcaps to maintain its authentic delivery appearance. Heavy-duty metallic power brakes with cooling fans were part of the Z06 equipment to prevent fade during endurance events. The body panels show the quality expected of a Top Flight award winner with excellent fit and finish. Every line on this Sting Ray serves both an aesthetic and aerodynamic purpose. It captures the transition of the Corvette from a boulevard cruiser to a world-class performance machine. Consequently, it remains the most recognizable silhouette in American sports car history.
Refined Blue Interior and 36-Gallon N03 Tanker Capacity
Inside the cabin, the 1963 Chevrolet Corvette Z06/N03 offers a purposeful environment finished in a matching blue vinyl. While many race-spec cars were stripped of luxuries, this example retains power windows and a pushbutton AM/FM radio. The most defining interior feature is the massive N03 fuel tank positioned behind the seats. This 36-gallon unit was engineered specifically to reduce pit stops during long-distance races like Sebring or Daytona. Occupants sit in the iconic thin-back bucket seats that defined the first year of the C2 generation. A four-speed manual shifter sits within the center console, providing a direct mechanical connection to the powertrain. The dashboard features the classic large-diameter tachometer and speedometer that were standard for fuel-injected models. This Corvette comes with its original warranty booklet and owner’s manual packet for complete documentation. Restoration photos are also provided to verify the work done to achieve its NCRS status. It offers a cockpit that feels both exceptionally rare and surprisingly refined for its racing pedigree. This interior is a sanctuary for any purist who values factory-correct details.
327/360 HP Fuel-Injected V8 and Performance Specs
The mechanical heart of this 1963 Chevrolet Corvette Z06/N03 is the legendary RF-suffix 327 cubic-inch V8 engine. This fuel-injected powerplant was factory rated at an impressive 360 horsepower and 352 lb-ft of torque. It features the advanced Rochester fuel injection system, which provided superior throttle response over contemporary carbureted rivals. As an original matching-numbers unit, it represents a nearly impossible find among the small population of Z06 tankers. Power is sent to the rear wheels via a close-ratio four-speed manual transmission and a heavy-duty rear end. The Z06 package also included a specialized cooling system to handle the heat of sustained high-speed competition. It delivers a visceral, high-revving soundtrack that is unique to the early small-block fuelie Corvettes. This engine allowed the split-window coupe to dominate its class in SCCA racing during the early 1960s. It remains a masterclass in naturally aspirated performance and mechanical efficiency. This specific drivetrain has been inspected by Z06 authorities to confirm its incredible authenticity. It is the defining feature that places this car in the top tier of all surviving Corvettes.
