The Chevelle, first introduced in 1964, was Chevrolet’s version of the corporate A-body at General Motors. The horsepower available in the SS model steadily increased through the 1960s, culminating in 1970 with the LS6 Turbo-Jet 454 V-8 option that is featured on this car, never to be eclipsed in subsequent years. The big block motor produced an advertised 450 horsepower at 5,600 rpm and 500 foot-pounds of torque at 3,600 rpm, which were the highest performance numbers of the muscle car era. Keep in mind this was a factory option that anybody could walk in and order from your friendly Chevrolet dealer for just an extra $263.30 on the window sticker. Some 4,475 buyers made that choice and were rewarded with higher insurance premiums to go along with the high performance. In fact, the car was rumored to produce 500 horsepower, but the factory claimed 450 in the interest of lower insurance costs. Hot Rod magazine tested an LS6 at the time and reported a blistering 13.44-second-quarter mile at a speed of 108 mph, utilizing 8.4 mpg of premium fuel. The tester noted the biggest problem was trying to get the tires to hook up, as any stab of the throttle caused them to go up in smoke and slide sideways as a result.

This exceptional example of Chevrolet’s ultimate expression of the muscle car was built at the Baltimore assembly plant and shipped on February 12, 1970, to Dean Myers Chevrolet-Oldsmobile in Toronto, Ontario, Canada. It is 1 of only 231 of these cars imported for sale in Canada, according to documents that accompany the car. It is factory equipped with the highly desirable Z15 SS Package featuring the monstrous LS6 454 cubic-inch, 450 HP “Big-Block” V-8 engine, F41 special suspension, Goodyear Polyglas F70-14 tires on five-spoke SS wheels and SS badging. The list of factory options ordered new on this Chevelle SS includes a TH400 automatic transmission, 4:10 ratio Positraction differential, bucket seats, center console, tinted glass, power steering and power front disc brakes, pushbutton AM radio and a heavy-duty battery. Treated to a comprehensive frame-off restoration starting with a walnut-blasting of the body and frame down to bare metal, the restoration utilized NOS parts wherever possible. The sheet metal was replaced as necessary and the completed body was sprayed in original-code Cortez Silver base/clear coat with black stripes. The correct LS6 454/450 HP V-8 engine, transmission and rear axle housing were rebuilt and properly detailed. Attention to detail is present in such items as the correct Holley four-barrel carburetor, deep-groove pulleys, emission controls, cooling-system components and spiral shock absorbers, all the right numbers and date codes, as well as careful placement of all the correct factory labels and markings.

This Chevelle checks many boxes: the one-year-only powerful LS6 engine, an attractive color combination, documentation, a superb restoration, proper care and perhaps most important of all, the most powerful Chevrolet muscle car ever produced.
