The Chevrolet Turbo-Thrift engine is a straight-six produced from 1962 to 2001 by the Chevrolet division of General Motors. The entire series of engines was commonly called Turbo-Thrift, although the name was first used on the 230 cubic inch version that debuted in 1963. The new engine featured seven main bearings in lieu of the four bearing design of its predecessor, the "Stovebolt" engine, and was considerably smaller and approximately 100 lbs lighter.
