CHEVROLET CORVETTE 1967 STING RAY




HISTORY

Still, the 1967 Corvette was a Sting Ray refined to the limit "the very best of the five year run and quite possibly the best Corvette ever". It was certainly the cleanest Sting Ray ever, though 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, and thus unique, was a single backup light, mounted above the license plate. The previous model's old fashioned wheel covers gave way to slotted six inch rally wheels with chrome beauty rings and lug nuts concealed behind small chrome caps. Interior alterations were likewise modest and included revised upholstery, and the handbrake moved from beneath the dash to between the seats. The convertible optional hardtop was no dubiously offered with a black vinyl cover, which as a fad among all cars at the time

The Powertrain changed hardly at all. The two small block V-8's returned, as did the 390 bhp big block. But the top two 427's now developed 400 and 435 bhp with a switch to triple two barrel carburetors. As before, they differed in compression ratios 10.25:1 and 11.0:1. The solid lifters and transistorized ignition that went on the 425 bhp unit. The latter, RPO L71, was also available with special aluminum heads replacing the cast iron one's and larger diameter exhaust valves as RPO L89 though with the same grossly understated horsepower.

The ultimate Corvette engine for 67 was coded L88, which was an even wilder L89 that 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 cam, aluminum radiator, small diameter flywheel, stratospheric 12.5:1 compression, and a single huge Holley four barrel carburetor. The result was no less than 560 bhp, again at 6400 rpm. Only one problem:  You had to use 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 additional $1,500 over the base $4,240.75 price. The L88 engine and required options were sold to a mere 20 power-hungry buyers that year.
