Description
The Corvette Sting Ray Convertible with the 375-horsepower big-block V8 represents the first year Chevrolet offered its new 396-cubic-inch engine in the Corvette lineup. Under the sculpted hood, the L78 396 carried forged steel crank and connecting rods, a high-lift hydraulic camshaft, and a high-flow intake manifold feeding a single four-barrel carburetor. Despite its single-carburetor layout, careful tuning and a compression ratio of 10.25:1 delivered one of the most potent factory Corvette engines up to that point, with broad torque from idle to its 5,200-rpm redline.
Styling for the 1965 Sting Ray Convertible remained true to the mid-generation C2 design, but subtle cues celebrated the arrival of big-block power. A slightly more pronounced cowl induction hood hinted at the engine’s increased displacement, while side coves and sculpted fender lines flowed uninterrupted into the doors and rear quarters. The convertible retained its power-operated soft top, which folded neatly behind the rear seats, and buyers could still opt for the detachable hardtop for improved insulation and a coupe-like profile.
On the road, the 375-hp Sting Ray Convertible felt muscular yet refined. The independent double-wishbone front suspension and transverse leaf-spring rear setup managed the extra weight of the big block without sacrificing agility. Optional power steering and power brakes helped rein in the car’s increased performance, while standard front disc brakes provided confident stopping power. With the optional close-ratio four-speed manual transmission, 0–60 mph took just over six seconds, and the Corvette’s long gearing meant cruising at highway speeds felt effortless.
Inside, the cockpit balanced performance cues with increasing comfort. Deeply bolstered bucket seats came trimmed in vinyl or optional leather, and the twin-cowl dash featured large, driver-oriented gauges, including a factory tachometer. Options such as air conditioning, an AM/FM radio, and rear lap belts added to the car’s touring credentials. Although the big-block Corvette carried a modest weight penalty compared to small-block models, its broad power delivery and refined chassis tuning made it an excellent grand tourer.
Today, the 1965 375-hp Sting Ray Convertible is prized among collectors as the model that bridged the gap between small-block performance and the later era of 427-cubic-inch engines. Its combination of rarity, historic significance, and visceral big-block character continues to draw admiration at vintage-car events and concours shows. As the first Corvette to wear the 396 badge, it stands as a testament to Chevrolet’s commitment to pushing performance boundaries in the mid-1960s.
