In 1968, there was major restyling for the entire period of production models. Wheelbase was shortened by three inches, the hood stretched rear Windows were converted, and became like a fastback body style. 396-e engines with 325 and 350-HP configured so that you do not succumb to 375-horsepower BHP L78. Relationships become dealer of axis 2.73: 1 to 4.88: 1, but problems remained with suspension, like the models of yesteryear. In 1969, the SS-396 again became the batch option for all models Chevelle. Engines offered are the same — 396-325 e-w, 350 or 375-n "horses", but still the weak link was the suspension. Later that year, 396-402-MI were replaced to match the next new standards. But officially the name and marks of power have not changed, and the Chevelle SS-396 remained one of the most popular "muscle cars", though with a different volume under the hood. And because of the large and regular interest of drag racers to Chevelle limited edition was published several special editions that are now highly sought after. For example, COPO Chevelle that shipped only to several dealers and Chevrolet was completed with 427 L72 engine blocks, developing 425 HP of such machines was built around 323 pieces and they very quickly found their buyers. in 1970, the year the new modification-LS6 issuing 450 BHP at 454 cubic inches in volume. It was the most powerful production engine in the Muscle Car era. Externally, the Chevelle too gradually in the year 1970. The rear part of the car, on an ad-hoc fashion of those years was V-shaped, a air intakes operate even on base models and top models were dressed on the bus 5-split spoke wheels Rallye. In 1971, began to surface emission standards for car exhaust, the first fuel crisis and fears about car insurance laws. Standard engine for Chevelle in 1971, was 350 M3 V8 giving scant 245 HP, with a single exhaust pipe. The same engine was available, the 270 forces but is not saved. 402nd engine, which is still marketed as 396, was renamed the Turbo Jet 400, and was rated at only 300 "horses", instead of 350, which he used to be. Version rated at 375 HP just became unavailable, LS6 454 just disappeared and LS5 454, with a capacity of 365 HP, became her very quickly lose. Index of SS-454 was only the LS5 engine models, the rest were just a couple of the letters "SS" 1972 year even more simplified the Chevelle SS SS package must be ordered now on any V8-engine with Chevelle. It turned out that you could buy a Chevelle SS 307 V8 with scarce 130 HP to deal General Motors should reduce engine power, in the end what happened that 350 V8 dropped to-175 HP, 2nd up to 240 402 and 454 to 270 troops. For fans of power have come on hard times, and the year was 1973, and was the last model of the Chevelle. Awful is the fact that the SS package was available even for a Chevelle station wagon. The design has been completely redesigned, and deforsirovany is the most powerful engines gave out 245 of the force, and the base model has been powered by "ridiculous" power 145 BHP L65 Chevrolet Chevelle was remembered by Americans as one of the legendary and affordable Muscle Car, the hero of racetracks and street drag racing.
