1971 Chevrolet Corvette

1971 Chevrolet Corvette Stingray Convertible â?" 350/270, Muncie 4-Speed, St. Louis Build Why This Car Is Special The 1971 Chevrolet Corvette Stingray Convertible occupies a unique position in C3 history. It was the last model year before GM's compression ratio cuts took full effect across the lineup, and as a result, the 1971 Corvette still carried factory power ratings that buyers in later years could only look back on with envy. The 350ci small block in this car was factory rated at 270 horsepower â?" a number that holds up well even by today's standards for a naturally aspirated engine of this displacement. By 1972, net horsepower ratings replaced gross figures across the industry, and the perception of Corvette performance shifted dramatically.
