Chevrolet Stovebolt engine

The Chevrolet Stovebolt is a straight-six that the Chevrolet Division of General Motors built in two versions between 1929 and 1962. It replaced Chevrolet's inline-four in 1929 and was mocked as the Cast-Iron Wonder and Stovebolt Six for its old-fashioned overhead-valve design, yet was advertised as a six for the price of a four and helped Chevrolet win back the sales lead from Ford. The first generation, from 1929 to 1936, had three main bearings and came in 181, 194 and 207 cubic inch sizes. The second generation, from 1937 to 1962, was re-engineered with four main bearings and grew to 216, 235 and 261 cubic inches. It is often called the Blue Flame, a name officially applied from 1953 to the 235 teamed with Powerglide, and Toyota's first engine, the Type A, was a reverse engineered copy of the 207. General Motors kept building it in Brazil until 1979, and the Turbo-Thrift replaced it.
