Chevrolet had five different full-size series and nineteen different models for 1966, including the Impala and Impala Super Sport (SS). Triple taillights made Impalas immediately discernable from other full-size Chevys, which had two taillights per side.
The Super Sport model gained famed a few years earlier with a 409-horsepower engine that was tough to beat on the drag strip or stock car track. For ’66, the Super Sport’s top engine was a 425-hp 427 “big block” V-8. This example features a 390-hp version of the 427 engine.
Visually, the Impala Super Sport included SS front fender emblems, Impala SS-accented grille and rear deck badge, SS full wheel covers, vinyl-covered bucket seats and a center console. They were offered in convertible and two-door hardtop body styles.
Approximately 1,603,000 full-size Chevrolets were produced in 1966, including 119,300 examples of the Impala SS.
FAST FACT: A 6-cylinder was the base engine in the ’66 Impala SS, but customers clearly preferred the V-8. Only about 900 6-cylinder SS models were sold – a mere 0.007-percent of the total production.
