As with before, the upholstery was revised and the seats were a new design. The hand brake (parking brake) was relocated from beneath the dashboard to between the seats – a Corvette first. While the inner doors remained largely the same as before, the lock buttons were moved further forward and an attaching screw was added at the rear. Perhaps the most notable change to the 1967 Corvette’s interior was the removal of the passenger hand-hold above the glovebox, a feature that had been part of the Corvette since <a href="https://www.corvsport.com/Corvette/C1/1957-1961/C1_1958_Overview.html" target="_blank">1958</a>.</p><p></p><p>The convertible’s optional hardtop offered with a black vinyl cover, which had been a fad amongst the automotive industry as a whole during that time.</p><p></p><p><img src="https://www.corvsport.com/wp-content/uploads/2017/01/3-33.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></p><p><em><span style="font-size: 12px">The 1967 Sting Ray’s interior received only minor updates for the final year of the second-generation Corvette.</span></em></p><p>Even fewer changes were made to the ‘67’s powertrain. As with the previous year, the two small-block V-8 engines returned, as did the 390 horsepower big-block, though this last engine was fitted under a redesigned hood scoop. The biggest changes involved the pair of big-block 427 engines, which now produced 400 and 435 brake horsepower respectively, due to the introduction of triple two-barrel carburetors. Like last year’s model, these new 427s differed in compression ratios – 10.25:1 and 11.0:1 respectively. The latter of these two engines, RPO L71, also included optional specialized aluminum heads (instead of cast iron) and larger-diameter exhaust valves like those included in RPO L89. Also as with previous years, the actual (true) horsepower of these behemoths was largely understated. WOW what a ride this would have been...</p><p></p><p style="text-align: center"><strong><em><span style="font-size: 18px">DID YOU KNOW: </span></em></strong></p> <p style="text-align: center"><strong><em><span style="font-size: 18px">While there are many unique identifiers that single out any model year of Corvette, the 1967 Sting Ray has a unique identifier to help set it apart – If you know where to look. A blue, “GM Mark of Excellence” label was attached to the back of each 1967 Corvette door above the latch. This initiative was the direct result of General Motor’s quality awareness program. Additionally, safety legislation required a modification of the knock off wheel option. For the 1967 model year, the wheels were changed to a bolt on, cast alloy style with a clip on center cap to conceal the lug nuts.</span></em></strong></p> <p style="text-align: center"></p><p>Based on the already impressive L89 engine, <a href="https://www.corvsport.com/Glossary/Corvette/Corvette_Glossary_C.html" target="_blank">Chevrolet</a> decided to introduce the “ultimate” Corvette engine in 1967 by introducing an engine coded with the designation L88. The L88 engine was an immensely powerful production engine, and was about as close to a pure racing engine as any <a href="https://www.corvsport.com/Glossary/Corvette/Corvette_Glossary_C.html" target="_blank">Chevrolet</a> had introduced in a commercial vehicle up to that point in time.</p><p>The big-block engine featured weight-saving aluminum cylinder heads mounted atop a standard Mark IV four-bolt iron block. The L88’s crankshaft was specially forged out of 5140 alloy steel, and was then cross-drilled for maximum lubrication and Tuftrided for hardness.</p><p></p><p><img src="https://www.corvsport.com/wp-content/uploads/2017/01/4-25.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></p><p><span style="font-size: 12px"><em>The 1967 Corvette featured an optional 400 or 435 horsepower 427 cubic inch engine.</em></span></p><p>Attached to the crankshaft via Magnafluxed connecting rods were eight forged-aluminum pop-up pistons that produced an air/fuel mixture at a staggering 12.5:1 compression ratio. Although General Motors claimed that it was no longer involved with racing (due to their commitment to support the Automobile Manufacturers Association’s ban on racing), there was no question that all twenty of these special L88 engines were intended for the racetrack. The L88 was yet another of Zora Arkus-Duntov’s unabashed attempts at elevating the Corvette to the stature of a race car, which is where he knew the Sting Ray ultimately belonged. However, when the engine was originally introduced to Corvette in the spring of 1967, the engine didn’t light the racing circuits afire as the L88 had durability problems early on in its career.</p><p>The engine was prone to overheating and utilized underrated (and inherently weak) connecting rods in the engine’s lower end. Nonetheless, the 1967 L88 equipped Corvette was definitely worth taking notice of, and proved that it had mastered the ability to go fast . At the 24 Hours of LeMans in June, 1967, a Corvette equipped with an L88 actually topped 170 miles per hour on the Mulsanne Straight before a connecting rod failed, thereby ending Corvette’s chance for a victory at the 24 hour race.</p><p>Of course, ordering the L88 production option meant more than just placing an order for an engine. When equipped with the L88 427 Corvette engine, the build also called for blank covers to replace both the AM/FM radio controls and the heating/cooling controls normally found in the center console of a ’67 Corvette’s dashboard. In fact, ordering the big-block 427 also meant the mandatory elimination of a radio head and power windows, as well as the elimination of a convenient automatic engine choke – though Chevrolet did have a retrofit hand-choke kit available for those drivers that could not get along without it.</p><p>In addition to the removal of some of the car’s creature comforts, other notable absences could be found under the hood. First, the fan shroud (which aids in engine cooling) was absent, as was any semblance of an emissions controls system.</p><p>There was no PCV (Positive Crankcase Ventilation) valve, but rather an obsolete road-draft tube that vented crankcase vapors directly into the atmosphere through the driver’s side valve cover. What was left instead was an impressive engine that was as perfectly suited to run on the racetrack.</p><p></p><p><img src="https://www.corvsport.com/wp-content/uploads/2017/01/6-15.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></p><p><em><span style="font-size: 12px">The 1967 Sting Ray was the only second-generation Corvette to run in the 24 Hours of Le Mans. </span></em></p><p>If ever an off-road engine option had been developed for the Corvette, this was it.</p><p>The L88’s ultra-high compression ratio left Chevrolet officials no choice but to warn owners about the car’s fuel consumption. The paperwork that was included with each Corvette equipped with the L88 option read “This unit operates on Sunoco 260 or equivalent gas of very high octane. Under no circumstances should regular gasoline be used.” A second label was placed inside the Corvette as well which similarly read “Warning: Vehicle must operate on a fuel having a minimum of 103 research octane and 95 motor octane or engine damage may result.”</p><p>Ultimately, sales of the L88 equipped Corvette were limited to a mere 20 units. While the car was immensely powerful, it was also an extremely expensive option. At an additional $1,500 over the base price of $4,240.75, the sticker shock proved too expensive for most enthusiasts, which was okay with GM since they had always felt that the L88 Corvette belonged on the racetrack.</p><p></p><p>As a whole, sales of the 1967 Corvette Sting Ray were down from earlier models. GM attributed most of the sales lag as a bi-product of the anticipated arrival of the Corvette’s overdue redesign. With a third generation Corvette just around the corner, the final year of the C2 Corvette still produced respectable sales numbers. In total, 22,940 units were sold, which was down over 5,000 units from the 1966 sales numbers, with the convertible accounting for nearly two-thirds of all sales with an impressive 14,436 units sold to the coupe’s meager 8,504 units. </p><p>Even as the sales numbers began to reach an end for the C2 Corvette, Chevrolet was ramping up for the introduction of its next-generation Corvette. While the introduction of the C3 Corvette would include the dis-continuation of the Sting Ray designation (an absence that was more than five years in the making,) the new Corvette would continue to retain a marine-based designation, though this time as a nickname. As 1968 approached, General Motors was about to unveil the “Shark”, and its unveiling would usher in another challenging era for both the Corvette and late-1960’s America.</p><p></p><p><img

[QUOTE="ddgermann, post: 114875, member: 3537"] Been busy the last couple of days but today lets look at the 1967 Corvette. The last of the C2 generation.

Perhaps the most notable change to the 1967 Corvette’s interior was the removal of the passenger hand-hold above the glovebox, a feature that had been part of the Corvette since [URL='https://www.corvsport.com/Corvette/C1/1957-1961/C1_1958_Overview.html']1958[/URL]. The convertible’s optional hardtop offered with a black vinyl cover, which had been a fad amongst the automotive industry as a whole during that time.

As with the previous year, the two small-block V-8 engines returned, as did the 390 horsepower big-block, though this last engine was fitted under a redesigned hood scoop. The biggest changes involved the pair of big-block 427 engines, which now produced 400 and 435 brake horsepower respectively, due to the introduction of triple two-barrel carburetors. Like last year’s model, these new 427s differed in compression ratios – 10.25:1 and 11.0:1 respectively. The latter of these two engines, RPO L71, also included optional specialized aluminum heads (instead of cast iron) and larger-diameter exhaust valves like those included in RPO L89. Also as with previous years, the actual (true) horsepower of these behemoths was largely understated. WOW what a ride this would have been... [CENTER][B][I][SIZE=5]DID YOU KNOW: While there are many unique identifiers that single out any model year of Corvette, the 1967 Sting Ray has a unique identifier to help set it apart – If you know where to look. A blue, “GM Mark of Excellence” label was attached to the back of each 1967 Corvette door above the latch. This initiative was the direct result of General Motor’s quality awareness program. Additionally, safety legislation required a modification of the knock off wheel option. For the 1967 model year, the wheels were changed to a bolt on, cast alloy style with a clip on center cap to conceal the lug nuts.[/SIZE][/I][/B] [B][I][SIZE=5][/SIZE][/I][/B][/CENTER] Based on the already impressive L89 engine, [URL='https://www.corvsport.com/Glossary/Corvette/Corvette_Glossary_C.html']Chevrolet[/URL] decided to introduce the “ultimate” Corvette engine in 1967 by introducing an engine coded with the designation L88. The L88 engine was an immensely powerful production engine, and was about as close to a pure racing engine as any [URL='https://www.corvsport.com/Glossary/Corvette/Corvette_Glossary_C.html']Chevrolet[/URL] had introduced in a commercial vehicle up to that point in time. The big-block engine featured weight-saving aluminum cylinder heads mounted atop a standard Mark IV four-bolt iron block. The L88’s crankshaft was specially forged out of 5140 alloy steel, and was then cross-drilled for maximum lubrication and Tuftrided for hardness. [IMG]https://www.corvsport.com/wp-content/uploads/2017/01/4-25.jpg[/IMG] [SIZE=3][I]The 1967 Corvette featured an optional 400 or 435 horsepower 427 cubic inch engine.[/I][/SIZE] Attached to the crankshaft via Magnafluxed connecting rods were eight forged-aluminum pop-up pistons that produced an air/fuel mixture at a staggering 12.5:1 compression ratio. Although General Motors claimed that it was no longer involved with racing (due to their commitment to support the Automobile Manufacturers Association’s ban on racing), there was no question that all twenty of these special L88 engines were intended for the racetrack. The L88 was yet another of Zora Arkus-Duntov’s unabashed attempts at elevating the Corvette to the stature of a race car, which is where he knew the Sting Ray ultimately belonged. However, when the engine was originally introduced to Corvette in the spring of 1967, the engine didn’t light the racing circuits afire as the L88 had durability problems early on in its career. The engine was prone to overheating and utilized underrated (and inherently weak) connecting rods in the engine’s lower end. Nonetheless, the 1967 L88 equipped Corvette was definitely worth taking notice of, and proved that it had mastered the ability to go fast . At the 24 Hours of LeMans in June, 1967, a Corvette equipped with an L88 actually topped 170 miles per hour on the Mulsanne Straight before a connecting rod failed, thereby ending Corvette’s chance for a victory at the 24 hour race. Of course, ordering the L88 production option meant more than just placing an order for an engine. When equipped with the L88 427 Corvette engine, the build also called for blank covers to replace both the AM/FM radio controls and the heating/cooling controls normally found in the center console of a ’67 Corvette’s dashboard. In fact, ordering the big-block 427 also meant the mandatory elimination of a radio head and power windows, as well as the elimination of a convenient automatic engine choke – though Chevrolet did have a retrofit hand-choke kit available for those drivers that could not get along without it. In addition to the removal of some of the car’s creature comforts, other notable absences could be found under the hood. First, the fan shroud (which aids in engine cooling) was absent, as was any semblance of an emissions controls system. There was no PCV (Positive Crankcase Ventilation) valve, but rather an obsolete road-draft tube that vented crankcase vapors directly into the atmosphere through the driver’s side valve cover. What was left instead was an impressive engine that was as perfectly suited to run on the racetrack. [IMG]https://www.corvsport.com/wp-content/uploads/2017/01/6-15.jpg[/IMG] [I][SIZE=3]The 1967 Sting Ray was the only second-generation Corvette to run in the 24 Hours of Le Mans. [/SIZE][/I] If ever an off-road engine option had been developed for the Corvette, this was it. The L88’s ultra-high compression ratio left Chevrolet officials no choice but to warn owners about the car’s fuel consumption. The paperwork that was included with each Corvette equipped with the L88 option read “This unit operates on Sunoco 260 or equivalent gas of very high octane. Under no circumstances should regular gasoline be used.” A second label was placed inside the Corvette as well which similarly read “Warning: Vehicle must operate on a fuel having a minimum of 103 research octane and 95 motor octane or engine damage may result.” Ultimately, sales of the L88 equipped Corvette were limited to a mere 20 units. While the car was immensely powerful, it was also an extremely expensive option. At an additional $1,500 over the base price of $4,240.75, the sticker shock proved too expensive for most enthusiasts, which was okay with GM since they had always felt that the L88 Corvette belonged on the racetrack. As a whole, sales of the 1967 Corvette Sting Ray were down from earlier models. GM attributed most of the sales lag as a bi-product of the anticipated arrival of the Corvette’s overdue redesign. With a third generation Corvette just around the corner, the final year of the C2 Corvette still produced respectable sales numbers. In total, 22,940 units were sold, which was down over 5,000 units from the 1966 sales numbers, with the convertible accounting for nearly two-thirds of all sales with an impressive 14,436 units sold to the coupe’s meager 8,504 units. Even as the sales numbers began to reach an end for the C2 Corvette, Chevrolet was ramping up for the introduction of its next-generation Corvette. While the introduction of the C3 Corvette would include the dis-continuation of the Sting Ray designation (an absence that was more than five years in the making,) the new Corvette would continue to retain a marine-based designation, though this time as a nickname. As 1968 approached, General Motors was about to unveil the “Shark”, and its unveiling would usher in another challenging era for both the Corvette and late-1960’s America.
