Exterior: Marlboro Maroon
The 1967 Corvette Sting Ray was the last Corvette of the second generation, and five years of refinements made it the best of the line. Although it was meant to be a redesign year, its intended successor the C3 was found to have some undesirable aerodynamic traits. Duntov demanded more time in the wind tunnel to devise fixes before it went into production.
Changes were again modest: Five smaller front fender vents replaced the three larger ones, and flat-finish rockers sans ribbing conferred a lower, less chunky appearance. New was a single backup light, mounted above the license plate. The previous models' wheel covers gave way to slotted six-inch Rally wheels with chrome beauty rings and lug nuts concealed behind chrome caps. Interior alterations were modest and included revised upholstery, and the handbrake moved from beneath the dash to between the seats. The convertible's optional hardtop was offered with a black vinyl cover, which was a fad among all cars at the time. The 427 was available with a 1282 ft³/min (605 L/s) Holley triple two-barrel carburetor arrangement, which the factory called Tri-Power. The ultimate Corvette engine for 1967 was coded L88, even wilder than the L89, and was as close to a pure racing engine as Chevy had ever offered in regular production. Besides the lightweight heads and bigger ports, it came with an even hotter camshaft, stratospheric 12.5:1 compression, an aluminum radiator, small-diameter flywheel, and a single huge Holley four-barrel carburetor. Although the factory advertised L88 rating was 430 bhp at 4600 rpm, the true rating was said to be about 560 bhp at 6400 rpm. The very high compression ratio required 103-octane racing fuel, which was available only at select service stations. Clearly this was not an engine for the casual motorist. When the L88 was ordered, Chevy made several individual options mandatory, including Positraction, the transistorized ignition, heavy-duty suspension, and power brakes, as well as RPO C48, which deleted the normal radio and heater to cut down on weight and discourage the car's use on the street. As costly as it was powerful - at an additional $1,500 over the base $4,240.75 price - the L88 engine and required options were sold to a mere 20 buyers that year. With potential buyers anticipating the car's overdue redesign, sales for the Sting Ray's final year totaled 22,940, down over 5,000 units from 1966 results. Meanwhile, Chevrolet readied its third-generation Corvette for the 1968 model year.
