Description
The Corvette Sting Ray Convertible fitted with the 300-horsepower version of the 327 small-block V8 occupied the middle ground of Chevrolet’s 1963–64 performance offerings, pairing spirited power with open-air motoring. Unlike the base 250-hp model, this variant used a dual four-barrel “2×4” carburetor setup, a slightly hotter camshaft profile, and higher compression to deliver stronger midrange punch and a more aggressive exhaust note.
With the dual-quad induction and hydraulic-lifter cam, the 300-hp engine produced its peak torque low in the rev band, making throttle response immediate and flexible. Mated to the close-ratio four-speed manual transmission, the convertible could sprint from 0–60 mph in the mid-six-second range—impressive for its era—while the three-speed automatic remained an option for those preferring effortless cruising.
Structurally, the C2 convertible shared its coupe’s refined chassis: independent double-wishbone front suspension, a transverse leaf-spring rear setup, and four-wheel coil springs delivered a balanced, composed ride. Standard front disc brakes offered confident stopping power, and optional power steering and brakes further tamed the car’s performance. The fiberglass body and relatively short 96-inch wheelbase made the convertible feel remarkably agile, even when bent into tight turns.
Inside, the Sting Ray Convertible’s cockpit combined sport and comfort. Deeply bolstered bucket seats held occupants firmly during enthusiastic driving, while the twin-cowl dashboard placed large, clear instruments squarely in the driver’s view. Amenities such as air conditioning, an AM/FM radio, and a removable hardtop for cooler weather allowed owners to tailor their cars toward touring or weekend track use.
Today, the 300-horsepower Sting Ray Convertible is celebrated for its blend of accessible yet engaging performance, timeless styling, and the unmatched thrill of wind-in-your-hair driving. It represents a sweet spot in early Corvette history—powerful enough to satisfy enthusiasts, yet straightforward enough to remain approachable for classic-car collectors.
