In the Pantheon of American Muscle Cars, the Chevelle has staked a rock-solid position. When it first rolled off the production lines in 1964 you get it with 120hp V6 or, either a 283- or 327- V8, that with the SS set-up would produce 300 bhp. Chevrolet would continue to produce the Chevelle until 1977, during which time it would get ever-increasing boosts of horsepower during the muscle-car salad days of the late sixties, and reach the zenith of it’s performance in 1970 when it rolled off the line with 454 cubic-inches capable of turning out 450 horsepower. As with all muscle cars, the early ’70′s saw a continued roll-back on power thanks to higher fuel and insurance prices, as well as the introduction of smog equipment. When the Chevelle badge was retired in 1977 the basic chassis/body style carried on under the Malibu name–de-tuned and de-fanged.
