“C2: The Mid-year Corvette”

The second-generation Chevrolet Corvette (C2) only lasted for 5 short model years, 1963 through 1967, and yet is the most iconic, and certainly the most valuable of all Corvettes ever built. They call them a lot of things, 2nd-gen Corvettes, C2’s, Sting Rays and Midyear Corvettes. They were called ‘Midyear Corvettes’ or just ‘Midyears’ for short for decades until the Corvette started racking up more and more generations later in life. That’s when the C1 through C8 naming convention came along and just in time too. Before that, C1s were called ‘solid-axle Vettes’, the C2 was called Sting Ray and the C3 became known as ‘the Shark’ Confusing and inconsistent, because not everyone knew what kind of axle it had.

After 10 model years of the 1st-gen Corvette , or C1 (1953-1962) the car world was ready for an upgrade. The C1 was a primitive car. Barely a car, starting out in ’53, it had no roll-up windows, no outside door handles and no heater. But it had evolved into a full fledged car, and a respectable high-performance roadster with world-class looks, and America’s only sports car. But, to save money, Chevy had cobbled the Corvette together from existing parts in GMs vast inventory. Front and rear suspension, rear axle, steering and brakes were all ancient, having been designed in the late 1940s. The primitive kingpin front suspension and worm-and-roller steering were glaring weak spots in a world of ball joints and recirculating ball steering. The Corvette had aged past its obsolescence. Sales had been decent and climbing, although just a pittance compared to GMs volume models. The final year of C1 production, 1962, saw 14,531 Corvettes sold, its best year ever.

Another key influence on the need for a change was Zora Arkus-Duntov, the Belgian-born engineer and resident genius who worked his way up through the ranks of GM until they appointed him Chief Engineer for the Corvette program. Duntov was into racing and he wanted the Corvette to be the car to beat. So far the C1 had had lukewarm racing results, and while powerful, the handling just wasn’t there. He felt nothing short of a completely new, clean-sheet design could keep the Corvette relevant and competitive. He wanted this new Corvette to run with the best from Europe such as the Jaguar E-Type.

In 1959 GM’s Chief Stylist Bill Mitchell (who had just succeeded Harley Earl) had overseen the creation of a one-off showcar/concept car, the 1959 Stingray Racer. In 1960 the Stingray Racer (XP-87) was built and raced. It previewed the bold styling of the C2 with it’s sharp nose and tail, rising fenders with wheels tucked in just right. Everything was already in place.

During 1961 and ’62 full scale development began on the production car. Many major decisions had to be made right up front. Ditch the old ladder-type frame in favor of a modern perimeter frame? Retire the ancient leaf springs and solid rear axle and invent a new independent rear suspension setup? During this time the C2 Corvette was being developed under the code name “Q-model” or “Sting-Ray” The new 1963 Corvette was officially unveiled at the New York Auto Show and the Chicago Auto Show in September of 1962.

The new C2 was bristling with innovation. The independent rear suspension (IRS) made it to production, as did the perimeter frame, which allowed a lower seating position and center of gravity, not to mention greater rigidity. And the styling was radically changed, for the better. The new shape was like nothing else anywhere, but in fact the Jag XKE was a worthy comparison because the new C2 Corvette’s shape followed some of the same patterns, with long hood/short deck and pointed at both ends. It was gorgeous!

For the first time, the Corvette came in two body styles: Coupe and Convertible. And for its initial introduction in 1963, the new Corvette coupes got a ‘split window’, now legendary. Rumor has it that at the time making a compound-curved piece of safety glass that big was difficult and expensive and so they opted for two smaller windows with a split down the middle. The other reason they went with it is that Bill Mitchell loved it. However, many dealers and customers hated it because it impaired rearward visibility. And so it was ditched by the 1964 model year and continued through the rest of its generation this way. They looked good either way, but the split window was distinctive and still commands attention and high auction prices today.

Another bold styling feature was the hideaway headlights, a first on a Corvette. They completed the streamlined nose perfectly when closed. When they opened, they didn’t flip up, they rotated which kept the exposed headlights in place and minimally obstructive aerodynamically. They looked good either way, and people loved to watch them open and close.

Lots of exciting new performance and comfort options became available for the first time in a Corvette with the 2nd-generation. Power steering and air conditioning became available late in the 1963 model year (unavailable on certain engines), aluminum knock-off wheels could be optioned from 1964 on. Power windows made their first appearance in 1965, and those gorgeous factory side pipes were offered from 1965 through 1967. The Corvette was becoming a real car.

Under the hood, the C2 started out exclusively with the 327 ci small block V8. The W-series big block 409 was never considered because of its weight and bulk, and it was already on its way out. For 1963, the 327 came in 3 flavors, the base engine with 250 hp (RPO 469), the high-performance version with hotter cam and compression with 300 hp (RPO 469A), both using single 4-barrels, and the “Fuelie”. This last entry used Rochester’s futuristic Ramjet mechanical fuel injection in service since 1957, which had just been completely reworked for the C2, making 360 hp (RPO 579). Gone were the dual-quad setups of the C1.

For the 1964 model year, another engine was added to the lineup. RPO 469Z was a 327 with single 4-barrel, solid lifter cam, and higher compression making 365 hp. And to make sure that the Fuelie remained the top dog, they bumped its horsepower to 375 where it stayed until its demise after the 1965 model year.

One more engine was added to the option list for 1965. Chevy’s new Mark IV big block had just been released with 396 cubic inches and 425 hp, thanks to a hot solid-lifter cam, high compression and a big carb. Of course, as the world would soon learn, big blocks were very good at making big power. The added weight (some 200 pounds) changed the handling dynamics of the car, but people bought them anyway. 2,157 chose the 396 in 1965.

For 1966 the big block was enlarged to 427 cubic inches making 390 hp with single 4-barrel (L72), or 425 hp with single 4-barrel, a solid-lifter cam and higher compression (L36). The expensive, finicky Rochester fuel injected 327 was gone, replaced by the cheaper-to-build big block. But now the base 327 made 300 hp (L469) and the high-performance version with all the usual upgrades making 350 hp (L469A). Remember when it was a big deal when the 1957 Corvette Fuelie broke the one-horsepower-per-cubic-inch barrier? First time ever in an American production car and the Corvette did it, and it was a big deal. Now Chevy was doing better than that with nearly all it’s high-performance engines.

In 1967, the final year of the 2nd-gen Corvette, the 427 got something very special. Tri-Power was a system of three Rochester 2-barrels on a special aluminum manifold. Under light loads, it ran on just the center carburetor, getting good mileage. But nail it and the other two 2- barrels would kick in with more air than a big 4-barrel. The L71 made 435 hp, and this engine would continue on until 1969 in the 3rd-gen Corvette. It was the Corvette’s top street engine. But what about off the street? In other words, racing? The L88 was a very special 427 hand built in GMs Tonawanda engine plant with higher-than-normal quality control. They started with a special high nickel-iron block with 4-bolt mains, stronger internals, aluminum heads with larger ports and valves, a radical solid-lifter race cam, with a 12.5:1 compression ratio, topped off by an 850 Holley on top. They claimed it made 430 hp but it was more like 550 hp or more! Just 20 L88s were installed in the 1967 model year, and only in Corvettes. This engine would continue until 1969

Something else was new for 1967. The big block 427 was taller than its small block cousins so a new hood was created that added 4.5 inches of much-needed vertical clearance. It was called the “Stinger Hood” and it was very handsome and distinctive, with a wide scoop that had a ‘stinger’ coming out the front of it. They were so handsome that people started putting them all all their C2 Corvettes to improve the looks. Today these are a very common upgrade.

With all this power, how did the C2 Corvette fare in motorsports? It dominated SCCA amateur and professional racing, and Dick Thomas, known at ‘The Flying Dentist’ won three SCCA National Championships in 1963, 1964 and 1965. At the Sebring 12 Hours their best finish was a 6th overall in 1965, and competitive in all other years. They got numerous wins in GT and Prototype classes, and several finished in the top 10 overall at the Daytona Continental race. In 1966 a C2 piloted by Dan Gurney and Bob Bondurant finished 7th overall in the 1966 24 Hours of Le Mans, which was a private effort. The C2 also did well in short-track and drag racing.

This new 2nd-generation Corvette had it all: mega power, excellent handling and the looks. The 1st-gen’s low production numbers peaked in its final year of production (1962) with 14,531 sold. The C2, known then as the Sting Ray (2 words), did marginally better, but didn’t set the world on fire. In 1963 they sold 21,513 Vettes, in 1964 the number climbed to 22,229, then in 1965 it went to 23,562, in 1966 27,720 (it’s best year) and in its final year, 1967 sales actually dropped to 22,940. Over the 2nd generation, coupes outsold convertibles by a healthy margin (72,093 coupes to 45,871 convertibles). A grand total of just 117,964 Corvettes were built during its second generation.

Today the C2 is considered the most desirable by collectors as shown in the auction prices that they fetch. The current record stands at $3,850,000 for a 1967 L88 at Mecum’s Kissimmee sale in 2025. The top 4 sales of C2 Corvettes are all L88s. That’s not only the highest price ever gotten for a C2 Corvette, it’s the highest of any Corvette, regardless of year or generation. That’s the C2 legacy. And while the newer Corvettes are spectacular performers, they’re not classics, although maybe some day they will be. But for now, the world’s most valuable Corvettes in the world are all C2s.
