The 1963-1967 Corvette Sting Ray

The second generation Corvette was the 1963-1967 Sting Ray, not to be confused with the third generation 1968-82 Stingray (1 word). The styling was the expression of many styling ideas from new GM styling boss Bill Mitchell. The interior implemented a dual cockpit similar to previous Corvettes but updated for the Sting Ray. From 1963 the first hardtop coupe with a two-part rear window was offered. Bill Mitchell intended it to visually link to the central ridges on the hood. The feature was dropped in 1964 because it restricted rearward visibility. However, the 1963 Sting Ray coupe is now the most coveted model of the second generation Corvette.

As with all Corvettes, the Sting Ray’s body is constructed of fiberglass panels mounted on a steel ladder frame. Another new feature was the hidden dual pop-up headlights, which not only added style but also contributed to aerodynamic efficiency. Other Sting Ray styling cues include an optional side-mount exhaust, a performance bulge on the hood (this was wider on the big-block Corvettes) and the lack of a decklid (accessed from behind the seats). In addition, the Corvette’s convertible top folds down completely when not in use and stows beneath a flush-fitting fiberglass panel behind the driver. There was also an optional hardtop. Sting Ray models of different years can often be distinguished by their side vents, for example 1967 models had 5 side vents, 1965 and 1966 models had triple side vents, 1963-64 models had horizontal dual vents.

Sting Rays came in three engine sizes, the 327 cid, the 396 cid, and the 427 cid. The horsepower varied between 250 and 435 hp. The 396 engine was only offered in 1965 and was discontinued in 1966 in favor of the 427. The 1967 L88 427 cid V8 marked the pinnacle of performance for the second-generation Corvette. The V8 engines drive the rear wheels through a four-speed manual or three-speed automatic transmission. The Sting Ray also had an aluminum clutch housing and aluminum-cased gearbox to aid in weight reduction and weight distribution. The 1963 Sting Ray was the first Corvette with independent suspension. The 1965 was the first with 4-wheel disc brakes.

The 63 Corvette also had a racing option, the Z-06. The Z-06 was developed by Zora Arkus-Duntoz as a purpose-built racing car. The Z-06 option consisted of a fuel-injected 327 cid V8, 36.5-gallon fuel tank, heavy-duty brakes, heavy-duty suspension and knock-off wheels. The heavy-duty brakes consisted of drums with sintered metal pads, supported and assisted by a dual-circuit master cylinder. “Elephant Ear” blades rammed fresh air to the drums and cooling fans rotated with the hub.

Four versions of the 427 were available for 1967. The first version, the L36, was only $200 more and featured a single four-barrel carburetor, 10.25:1 compression and hydraulic lifters. It was rated at a whopping 390 hp. Next came the $305 L68, which featured triple-barrel Holley carburetors (a first for Corvette) and produced 400 horsepower. At the top was the L71 with triple two-barrel Holley carburetors, solid lifters, dedicated performance cams and 11:1 compression, which was conservatively rated at 435 hp. Extremely rare (only 20 were built) was the top-of-the-line L88 at $948 more. The L88 featured new aluminum heads, 12.5:1 compression ratio and a single Holley four-barrel carburetor rated at 850 cfm, sitting on an aluminum intake manifold with a special raised air chamber. You also have transistorized ignition and a positraction differential, but no fan shroud, heater, or defroster. Chevrolet was reluctant to reveal the engine’s true potential and officially only had 430 hp, but most experts believed that it actually developed almost 600 hp! A total of 9,707 big-blocks were built, meaning that 42.31% of all 1967 Corvettes were 427s. The means of transmission were relatively simple. On the L36 and L68, buyers could choose between the four-speed wide-ratio ($184) or narrow-ratio ($184) manuals or the Powerglide automatic transmission ($194). The L71 only came with the close-ratio four-speed. Rear-end gear ratios ranged from 3.08 to 4.11. Other options included side-mount exhausts for $132, bolt-on cast-aluminum wheels for $263, and a removable hardtop for the convertible for $232.
