1963 Buick Special
In 1961, Buick introduced an innovative, lightweight all-aluminum V-8 to power its new midsize Special model line. Displacing only 3.5L (215 cubic inches), it was lauded for its high power density. The engine achieved its peak in the 1963 Special, with its 200-hp output representing a horsepower-to-liter ratio of 0.93:1. Versions of the engine were used in Indy racing cars.
