The 1967 Corvette is the first year of the second generation, and the split rear window appears only in 1963

The 1967 Corvette is a significant car in Chevrolet's history, but it is not the split-window model. The split rear window—two separate panes of glass dividing the back window down the middle—appeared only in 1963, the first year of the second-generation Corvette. If you own a 1967 or are considering buying one, you have a single-pane rear window, not the iconic split design that collectors prize.

This matters because the split window became legendary almost when ready. Chevrolet's chief designer, Bill Mitchell, considered it a styling signature so important that he fought to keep it, even as engineers and other designers pushed for a single pane for better visibility and structural simplicity. The company dropped it after one year, making 1963 the only model year with that feature. Today, a 1963 split-window Corvette is worth significantly more than a 1967, and the confusion between the two years costs owners money when they buy, sell, or insure.

Key Takeaways

  • The split rear window exists only on 1963 Corvettes; the 1967 has a single rear window pane and belongs to the same generation but a different design era.
  • A 1963 split-window Corvette is worth roughly double or more what a comparable 1967 commands, so misidentifying the year is a costly mistake.
  • The 1967 Corvette introduced the L88 big-block engine option and other mechanical upgrades that make it valuable in its own right, separate from the split-window mystique.
  • Both years require regular cooling system maintenance, fuel system inspection, and attention to the fiberglass body, but a 1963 needs more careful restoration planning because parts are scarcer.

Why the 1963 split window became iconic and the 1967 did not

Bill Mitchell designed the split rear window as a visual accent that emphasized the car's width and gave the fastback roof a distinctive profile. The two panes created a vertical line down the center of the rear, making the Corvette look wider and more aggressive. Chevrolet marketed it as a design statement, and enthusiasts loved it when ready—so much so that when the company removed it in 1964 for practical reasons, the 1963 became the rarest and most sought-after Corvette of that era.

The 1967 Corvette, by contrast, arrived five years into the second generation and represented a mid-cycle refresh rather than a new design. It kept the fastback roofline and the overall shape, but the single rear window was standard across the entire lineup. The 1967 is valuable for its mechanical upgrades—particularly the L88 big-block engine and improved suspension—but it lacks the historical singularity that makes the 1963 a collector's trophy. For owners and buyers, this distinction is crucial: a 1967 is a solid, desirable classic, but it is not the split-window car.

What to check when you own or are considering a 1967 Corvette

The fiberglass body is the first place to inspect on any second-generation Corvette. Fiberglass does not rust, but it can crack, delaminate (separate into layers), or develop stress fractures around the doors, windows, and where the body meets the frame. Look for hairline cracks in the doors and quarter panels, and run your hand over the surface to feel for soft spots or areas where the gel coat (the outer protective layer) has worn through. Water can seep into cracks and cause the fiberglass to weaken from inside, so even small damage should be addressed.

The cooling system is the second priority. The 1967 Corvette's engine—whether the base 327 or the optional L88 big-block—runs hot, and the original cooling system was marginal even when new. Check the radiator for leaks or corrosion, inspect all hoses for cracks or soft spots, and confirm that the water pump is not weeping. If the car has been sitting, the coolant may be old and acidic, which eats through metal passages inside the engine. A fresh coolant flush and new hoses are preventive work that pays for itself by avoiding a cracked block or a seized engine.

The fuel system requires attention because gasoline has changed since 1967. Modern fuel contains ethanol and detergents that can gum up old carburetors and fuel lines. If the car has been stored, the fuel tank may have rust or sediment inside. The carburetor should be cleaned or rebuilt, the fuel filter replaced, and the lines inspected for cracks. A clogged fuel system will cause hard starting, hesitation, and stalling—all symptoms that feel like engine trouble but are actually fuel delivery problems.

Engine options and what they mean for maintenance

The 1967 Corvette came with three engine choices: the base 327 cubic-inch V8 (300 horsepower), the mid-range 327 (350 horsepower), and the legendary L88 big-block 427 (430 horsepower). The L88 was expensive and rare—only 20 were built for 1967—and it required premium fuel, a heavy-duty cooling system, and a four-speed manual transmission. If you own or are buying an L88 car, maintenance costs are higher because the engine runs hotter and harder than the smaller blocks.

All three engines share the same basic maintenance needs: regular oil changes, spark plug replacement, and ignition system inspection. The distributor, points, and condenser are mechanical components that wear and should be checked every few years. Timing should be verified with a timing light, because drift in the ignition timing causes hard starting and poor fuel economy. If the car has been converted to electronic ignition (a common and sensible upgrade), the maintenance is simpler, but you should still have the timing checked.

Transmission and drivetrain concerns specific to 1967 models

The 1967 Corvette offered a three-speed automatic or a four-speed manual transmission. The manual is more desirable to collectors and more fun to drive, but both require periodic attention. The clutch on a manual car should be inspected for wear; if the pedal feels spongy or the car lurches when you shift, the clutch may be near the end of its life. Transmission fluid should be checked and changed according to the manufacturer's interval—usually every 30,000 to 50,000 miles if the car is driven regularly.

The rear differential is another critical component. The 1967 used a solid rear axle with a limited-slip differential on most models. The differential fluid should be checked and changed regularly, because old fluid loses its lubricating properties and allows the gears to wear. If you hear a clunking sound when you accelerate or coast, or a whining noise at highway speeds, the differential may need service or repair. This is not a do-it-yourself job for most owners; a transmission shop can diagnose and fix differential problems.

Suspension and steering systems that age differently than modern cars

The 1967 Corvette has independent front suspension with coil springs and a solid rear axle with leaf springs. Both systems are simpler than modern suspensions but require regular inspection because the rubber bushings and ball joints wear over time. A clunking sound when you turn or go over bumps often means a worn ball joint or tie-rod end. Uneven tire wear suggests alignment problems or worn suspension components. Have the suspension inspected by a shop familiar with classic cars, because alignment specifications and adjustment procedures are different from modern vehicles.

The steering box is a mechanical unit that can develop play or looseness as it ages. If the steering wheel feels loose or the car wanders on the highway, the steering box may need adjustment or replacement. Power steering was optional on the 1967, and if your car has it, the pump and hoses should be checked for leaks. The power steering fluid should be flushed and replaced periodically, because old fluid becomes acidic and damages the pump seals.

Brake system maintenance for a car that stops differently than you expect

The 1967 Corvette has drum brakes on the rear and disc brakes on the front—a combination that was modern for the time but feels weak by today's standards. The front discs are prone to rust if the car sits for long periods, and the pads wear faster than modern brake pads because the system has to work harder to stop the car. The rear drums can develop internal corrosion and should be inspected regularly. If the brake pedal feels soft or sinks to the floor, the system may have air in the lines or a leak, and you should not drive the car until it is repaired.

Brake fluid should be flushed and replaced every two years, because brake fluid absorbs moisture from the air and becomes corrosive. Old brake fluid can cause the wheel cylinders and calipers to seize, which is expensive to repair. If you are planning to drive the 1967 regularly, consider upgrading to a modern brake fluid and having the entire system inspected by a shop that knows classic cars. Some owners upgrade to four-wheel disc brakes, which improves stopping power and reduces maintenance.

Frequently Asked Questions

Is my 1967 Corvette worth more if I restore it to original condition?

Not necessarily. A well-maintained 1967 in good original condition is valuable, but a thoughtfully restored car with modern upgrades (like electronic ignition, four-wheel disc brakes, or a more reliable cooling system) can be worth as much or more because it is more reliable and safer to drive. The market values both approaches; the key is doing the work well and documenting what you changed.

How often should I change the oil in a 1967 Corvette?

If you drive it regularly, every 3,000 miles or every three months, whichever comes first. The 1967 engine produces more heat and sludge than modern engines, and old oil breaks down faster. If the car sits for months between drives, change the oil before you store it and again before you drive it in spring. Use a high-quality oil rated for older engines; synthetic oil is fine if the engine has been rebuilt, but check the manual if the engine is original.

What should I do if the fiberglass body has a crack?

Small cracks in the gel coat can be sealed with epoxy or fiberglass repair compound from an automotive paint supplier. Larger cracks or delamination require professional repair by a shop experienced with fiberglass restoration. Do not ignore cracks, because water seeps in and weakens the structure. Get the damage assessed by a professional before it spreads.

Can I drive a 1967 Corvette in winter?

You can, but salt and moisture are hard on the fiberglass and undercarriage. If you live in a cold climate, store the car in winter or wash it frequently and explore a protective wax. The cooling system should be flushed and filled with fresh coolant rated for your climate. Check the battery regularly, because cold reduces its output and older batteries struggle to start the engine.

How do I know if my 1967 is a real L88?

Check the engine block casting number and the vehicle identification number (VIN) against Corvette documentation. The L88 has a specific block casting and a VIN code that identifies it as an L88 car. Only 20 L88 Corvettes were built in 1967, so verify the car's history with a Corvette club or a specialist before you buy. Misidentified or fake L88 cars are common in the used market.
