The 1967 Chevrolet Corvette Sting Ray is widely regarded as the finest of the C2 generation — the year the design was cleaned of five seasons of accumulated ornament and the engine bay reached its absolute peak. It was the last Sting Ray, the last of the mid-year Corvettes, and the year Chevrolet introduced the L88: a 427 big-block built for racing, deliberately under-rated at 435 hp when real output was somewhere between 540 and 580, and fitted to just 20 cars. Alongside it sat the L71 427/435 tri-power and the aluminum-head L89. For collectors the 1967 represents the C2 at its most refined and most ferocious at the same time.

Overview and History
The C2 Corvette had arrived for 1963 as a revelation: the first Corvette coupe, the first with independent rear suspension, and a body of extraordinary drama. Over the following five model years Chevrolet steadily improved it — four-wheel disc brakes and the first big-block in 1965, the 427 in 1966 — while simultaneously adding trim details that gradually cluttered Bill Mitchell’s original shape.
For 1967 the process reversed. Knowing a new generation was coming, Chevrolet stripped the ornamentation back, producing what many consider the cleanest and best-resolved version of the design. C2 production ran from August 1962 to July 1967, and the C3 that replaced it entered production in August 1967.
What makes 1967 exceptional is the combination. The styling is at its most refined, and the engine options are at their most extreme — the L88 appeared this year, the most uncompromising engine ever fitted to a production Corvette to that point.
The Final Sting Ray
1967 was the last year for the Sting Ray as two words. The C3 that followed revived the name for 1969 as a single word — Stingray — and the distinction matters to enthusiasts: a Sting Ray is a 1963–1967 car, a Stingray is a C3.
It was also the end of what collectors call the “mid-year” Corvettes, a term covering the 1963–1967 cars that sit between the C1 and the C3. These five model years are treated as a coherent and especially desirable era, and the 1967 closes it.
There is a note of accident in this too. The C3 had originally been intended for 1967, and delays pushed it back a year — meaning the 1967, like the 1957 Bel Air before it, is a car that exists because a replacement was not ready. In both cases the enforced extra year produced what is now considered the high point of the design.
Styling: Cleaner Than Ever
The 1967 revisions were subtractive, which is why they worked. The most visible change is at the front fenders, where the previous years’ vertical trim gave way to five functional slanted louvres on each side — clean, purposeful, and an instant 1967 identifier.
The hood scoop treatment on big-block cars changed to a distinctive forward-facing “stinger” design, with the L88 carrying its own unique hood. Wheel covers were replaced by cleaner bolt-on aluminum wheels or simpler covers, the badging was reduced, and the backup lights were relocated. The overall effect is a car that looks tighter and more serious than the 1965 or 1966.
Both body styles continued: the fastback coupe and the convertible, the latter available with an optional removable hardtop.
Engine Lineup
The 1967 range spanned a remarkable spread, from a civilized small-block to a barely street-legal race engine:
- 327 cu in small-block V8 — base engines, in several states of tune, suitable for road use and still the most usable choice
- 427 cu in, 390 hp — the entry big-block, available with manual or automatic
- 427 cu in, 400 hp — mid-range big-block
- 427 cu in L71, 435 hp — triple two-barrel carburetion, the top street engine
- 427 cu in L89, 435 hp — L71 with aluminum cylinder heads; just 16 built
- 427 cu in L88, 430 hp (advertised) — the full competition engine; just 20 built
Engine suffix codes on the block identify exactly which engine a car was built with — IP for 427/425 manual (an early 450 hp rating was briefly used), IQ and IR for the 390 hp automatic variants, JE and JA for the 435 hp L71, IU and JH for the aluminum-head L89 cars, and IT for the L88. These codes are the foundation of authenticating any 1967 big-block.
The L88
The L88 is the legend of 1967. Introduced that year, it was a highly modified 427 built for racing: aluminum cylinder heads, a very high compression ratio demanding fuel of at least 103 research octane, a radical camshaft, and essentially no concessions to comfortable road use.
Chevrolet rated it at 435 hp on paper — and then at 430 in some documentation — while actual output was somewhere between 540 and 580 horsepower. The under-rating was deliberate. By quoting a figure five horsepower below the L71’s 435, Chevrolet discouraged casual buyers from ordering an engine that would make a miserable street car, while racers who knew what it was ordered it anyway.
The car was equipped accordingly: the distinctive L88 hood, a heavy-duty M22 four-speed, performance suspension, Positraction, upgraded heavy-duty disc brake calipers, and transistorized ignition. Chevrolet even fitted warning labels instructing that regular gasoline must never be used and that the vehicle required a minimum of 103 research octane and 95 motor octane or engine damage could result. In stock form an L88 could run the quarter mile in the high eleven-second range.
Just 20 L88 Corvettes were built for 1967, and only 20 cars received the M22 gearbox — a figure that matches the L88 run exactly. Across all three L88 years production totalled 216 cars: 20 in 1967, 80 in 1968, and 116 in 1969. Many went racing immediately. A documented 1967 L88 is among the most valuable Corvettes in existence.
L71 Tri-Power and L89 Aluminum Heads
For buyers who wanted maximum street performance without the L88’s uncompromising nature, the L71 was the answer: a 427 with triple two-barrel carburetion rated at 435 hp. It is the classic 1967 big-block, genuinely fast, and far more usable on the road than an L88.
The L89 took the L71 and added aluminum cylinder heads, reducing weight over the front axle while retaining the 435 hp rating. Only 16 were built for 1967, making it rarer even than the L88 and a significant car in its own right.
Because the L71 and L89 share a horsepower rating, suffix codes and head castings are the way to tell them apart — another reason careful decoding matters on these cars.
Transmissions and Drivetrain
A four-speed manual was the enthusiast’s choice, with the heavy-duty M22 — the “Rock Crusher” — reserved for the L88. A three-speed automatic was available with the lower-output engines, and the suffix codes distinguish automatic from manual applications.
Positraction limited-slip was standard on the high-performance packages and widely specified elsewhere, with a range of axle ratios available. The independent rear suspension introduced in 1963 carried over, giving the car the traction to use its power.
Chassis and Brakes
The C2 chassis was at its most developed in 1967. The independent rear suspension — a transverse leaf spring with half-shafts acting as upper links — had been refined over five seasons, and four-wheel disc brakes, introduced for 1965, were standard.
That last point matters enormously relative to the 1963 car, which relied on drums. With discs all round, a 1967 is a far more confidence-inspiring car to drive quickly, and the L88’s heavy-duty calipers took that further still for competition use.
Power steering and power brakes were available, and the big-block cars carried stiffer springing and larger anti-roll bars to cope with the additional weight and power.
Interior
The cockpit followed the twin-cowl layout established in 1963, with a large speedometer and tachometer facing the driver and secondary gauges in the centre console. For 1967 the handbrake moved from under the dash to a conventional lever between the seats — a small but genuinely welcome change.
Seats were revised with improved support, and the overall trim quality was at its C2 best. Options ran to leather upholstery, air conditioning (not available with the highest-output engines), power windows, AM/FM radio, and a telescopic steering column.
Decoding a 1967
Given the value spread between a base 327 car and a documented L88, decoding is essential. A 1967 serial number such as 194677S109097 identifies the body style, model year, assembly plant, and sequence number — in that case a St. Louis-built 1967 convertible. The C2 used Series 194 designations from 1965 through 1967.
Engine suffix codes stamped on the block are the critical reference for identifying which engine a car left the factory with. The trim tag supplies paint and interior codes. Together with build documentation and tank sheets where they survive, these establish whether a car is what it claims to be.
One illustrative car: the first production 1967 L88, serial number 194677S109097, was a Tuxedo Black convertible — the only Tuxedo Black 1967 L88 convertible built — campaigned in period by Tony DeLorenzo. That level of individual documentation is typical of how closely these cars are tracked.
Collectibility Today
The 1967 sits at the top of the C2 market alongside the 1963 split-window coupe, and in big-block form it surpasses it. The value hierarchy runs: documented L88 at the summit, then L89, then L71 435 hp cars, then lesser 427s, with 327-powered cars the accessible entry point — though “accessible” is relative for any 1967 Corvette.
Convertibles and coupes both have strong followings, with the fastback coupe’s styling particularly admired in its final, cleanest form.
Authentication is the whole game. Verify engine suffix codes and casting numbers against the claimed specification; check head castings on cars presented as L89; confirm the M22 gearbox on an L88 claim; examine the trim tag and any surviving documentation; and have the fiberglass assessed by a specialist. The gap between a real L88 and a well-built tribute is measured in millions, which means professional verification is not merely advisable but mandatory at the top of this market.

1967 Chevrolet Corvette Sting Ray – Frequently Asked Questions
Why is the 1967 considered the best C2 Corvette?
Two reasons converge. The styling was cleaned up rather than added to — Chevrolet stripped away ornamentation accumulated over five years, producing the most resolved version of Bill Mitchell’s design, identified by the five slanted louvres on each front fender. At the same time the engine options reached their peak with the 427 in multiple forms, including the legendary L88. It is the C2 at its most refined and its most extreme simultaneously.
What is the L88 Corvette?
A 427 cu in big-block built for racing, introduced in 1967. It used aluminum cylinder heads, very high compression requiring a minimum of 103 research octane fuel, and almost no provision for comfortable road use. Chevrolet advertised it at 435 hp while actual output was between 540 and 580 hp — deliberately under-rated, and quoted below the L71’s rating, to discourage casual buyers. Only 20 were built for 1967.
How many L88 Corvettes were made?
216 across all three years: 20 in 1967, 80 in 1968, and 116 in 1969. The 1967 cars are the rarest and most valuable. A useful cross-check: only 20 1967 Corvettes received the heavy-duty M22 four-speed, matching the L88 production run exactly, since the M22 was part of the package.
What is the difference between L71, L89, and L88?
The L71 is the 427 with triple two-barrel carburetion rated at 435 hp — the top street engine, genuinely fast and usable. The L89 is an L71 fitted with aluminum cylinder heads, same 435 hp rating but less weight over the front axle; just 16 were built. The L88 is a different proposition entirely: a full competition engine with a radical camshaft, extreme compression, and a deliberately misleading power rating. Suffix codes and head castings distinguish them.
Is a Sting Ray the same as a Stingray?
No, and the distinction matters to enthusiasts. Sting Ray as two words applies to the 1963–1967 C2 cars. The C3 generation revived the name for 1969 as a single word, Stingray. The 1967 is therefore the last Sting Ray and the last of what collectors call the “mid-year” Corvettes.
Did the 1967 Corvette have disc brakes?
Yes — four-wheel disc brakes were standard, having been introduced for 1965 along with the first big-block. This is a significant practical difference from the 1963 and 1964 cars, which used drums all round. L88 cars received heavy-duty disc brake calipers as part of their competition package.
How do I authenticate a 1967 big-block Corvette?
Start with the engine suffix code stamped on the block — IT indicates L88, JE and JA the L71, IU and JH the aluminum-head L89, IP the 427/425 manual. Cross-reference casting numbers, check head castings on any L89 claim, and confirm the M22 gearbox on an L88. Examine the trim tag and any surviving build documentation. Given that the gap between a genuine L88 and a convincing tribute runs into millions, professional verification by a marque specialist is mandatory rather than advisable.
Why did the C2 end after 1967?
The C3 had originally been planned for 1967 but was delayed, pushing the C2 into a fifth and final season. C2 production ran to July 1967 and the C3 began in August 1967 for the 1968 model year. As with the 1957 Bel Air — another car that exists because its replacement was late — the extra year produced what is now widely regarded as the best version of the design.
