The 'LS' nomenclature originally came from the first engine of the Gen III engines, the LS1, which was fitted in the Chevrolet Corvette (C5). Various small-block V8s were and still are available as crate engines. Spanning three generations, a new, sixth generation is expected to enter production soon.
First 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 to be one of the most popular V8 engines ever.
The General Motors LS-based small-block engines are a family of V8 and V6 engines designed and manufactured by American automotive company General Motors.
