Chevrolet Stovebolt engine
The Chevrolet Stovebolt engine is a straight-six engine made in two versions between 1929 and 1962 by the Chevrolet Division of General Motors. It replaced the company's 171-cubic-inch (2.8 L) inline-four as their sole engine offering from 1929 through 1954, and was the company's base engine starting in 1955 when it added the small block V8 to the lineup. It was completely phased out in North America by 1962, but GM continued to build it in Brazil until 1979. It was replaced by the Chevrolet Turbo-Thrift engine.
