Chevrolet’s Super Sport Packages
The double S stands for Super Sport and it is Chevrolet’s prime designation for their performance models starting in 1961. Over the years, Chevrolet produced the Impala SS, Camaro SS, Nova SS and Chevelle SS, among others. In fact, they were even close to introducing a Corvette SS.
The SS package always meant the car came with the biggest engine it could house. In the case of the Impala, that was the 409 or 427 big block. In 1967, Chevrolet introduced the Camaro SS in two flavors, 350 and 396. They were competent muscle cars with lots of power in a compact, pony car package. So, if you are looking for a classic Bow Tie muscle car, the SS is the option to have.
