1929 Chevrolet with Stovebolt Six Engine
Introduced in the successful 1929 Chevrolet passenger car and truck lines that gave Ford fits, the "stovebolt" six got its initially derisive nickname from the appearance of the slotted-screw fasteners were used to secure its valve cover, timing cover and water pump. Chevrolets equipped with the inexpensive to manufacture and incredibly reliable engine quickly ate into Ford Motor Company's dominance at the low end of the market, offering "the power of six cylinders for the price of a four." The '29 Chevys were otherwise unremarkable, but the stovebolt inline-six had an enviable life, successfully transitioning through numerous technical redesigns and displacement changes that ranged from 3.2 to 4.8 liters. Among the most notable derivations was the 155-horsepower/235-cubic inch "Blue Flame Six" version used in the 1953 Corvette. The iconic engine remained a mainstay of the Chevy division until being mustered out of service in the late '80s.
