General Motors has built more than 100 million “small-block” V-8s since introducing the legendary motor family in 1955 to do battle in Detroit’s escalating horsepower war.

Since then, small-block V-8s have powered family sedans, arriving in time for the iconic ’55 Chevys and later the Malibu SSs and Camaros of the 1960s – and Le Mans winners, giving Corvette its first class win in 1960 and seventh in 2011, along with countless other forms of competition machines from NASCAR stockers to drag racers.
