The General Motors LS-based small-block engines are a family of V8 and offshoot V6 engines designed and manufactured by the American automotive company General Motors. Introduced in 1997, the family is a continuation of the earlier first- and second-generation Chevrolet small-block engine, of which over 100 million have been produced altogether and is also considered one of the most popular V8 engines ever. Spanning three generations, a new, sixth generation is expected to enter production soon. Various small-block V8s were and still are available as crate engines.
The Chevrolet small-block engine is a series of gasoline-powered V8 automobile engines, produced by the Chevrolet division of General Motors in two overlapping generations between 1954 and 2003, using the same basic engine block. Referred to as a "small-block" for its size relative to the physically much larger Chevrolet big-block engines, the small-block family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) in displacement. Engineer Ed Cole is credited with leading the design for this engine. The engine block and cylinder heads were cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The Buick V6 is an OHV V6 engine developed by the Buick division of General Motors and first introduced in 1962. The engine was originally 198 cu in (3.2 L) and was marketed as the Fireball engine. GM continued to develop and refine the 231 cu in (3.8 L) V6, eventually and commonly referred to simply as the 3800, through numerous iterations.
The Oldsmobile V8, also referred to as the Rocket, is a series of engines that was produced by Oldsmobile from 1949 until 1990. The Rocket, along with the 1949 Cadillac V8, were the first post-war OHV crossflow cylinder head V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were assembled at plants in Lansing, Michigan while the engine block and cylinder heads were cast at Saginaw Metal Casting Operations.
The Oldsmobile Diesel engine is a series of V6 and V8 diesel engines produced by General Motors from 1978 to 1985. Their design was based on the Olds 350 gasoline engine architecture. A 350 cu in (5.7 L) V8 was introduced in 1978, followed by a 261 cu in (4.3 L) V8 only for the 1979 model year. In 1982, a 263 cu in (4.3 L) V6 became available for both front front-wheel drive and rear-wheel drive vehicles.
The Buick V8 is a family of V8 engines produced by the Buick division of General Motors (GM) between 1953 and 1981. All were 90° water-cooled V8 OHV pushrod engines, and all were naturally aspirated except one turbocharged version of the 215.
The 122 engine was designed by Chevrolet and was used in a wide array of General Motors vehicles. The 122 was similar to the first two generations of the General Motors 60° V6 engine; sharing cylinder bore diameters and some parts. The 122 was available in the U.S. beginning in 1982 for the GM J platform compact cars and S-series trucks.
The Pontiac straight-8 engine is an inline eight-cylinder automobile engine produced by Pontiac from 1933 to 1954. Introduced in the fall of 1932 for the 1933 models, it was Pontiac's most powerful engine at the time and the least expensive eight-cylinder engine built by an American automotive manufacturer. During its 21-year run displacement of the "eight" increased twice as platforms grew. It was superseded by Pontiac's new V8, the 287, in 1955. Engine block and cylinder heads were cast at Saginaw Metal Casting Operations then assembled at Tonawanda Engine before delivery to Pontiac Assembly for installation.
GMC has both shared engine designs and architectures with other General Motors divisions as well as having a history of developing and using its own unique engines and powertrains such as its line of straight-6 and V8 engines.

The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu. The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans. Its phaseout marks the end of an era of Chevrolet small-block engine designs dating back to the 1955 model year. A new Generation V 4.3 L (262 cu in) V6 variant entered production in late 2013, based on the LT1 small block V8 and first used in the 2014 Silverado/Sierra 1500 trucks.
