An LS swap is a type of engine swap using any form factor of General Motors's LS V8 engine series.[1][2] Motor Trend noted in 2020 that "the Chevy LS V-8 engine has become the de facto engine swap suggestion for anyone seeking to add power to their existing platform" due to the engine's relatively compact size and light weight.[3] LS swaps have been performed since the introduction of GM's LS1 engine in 1997. Widespread aftermarket support for LS swaps has developed in subsequent years.[4]
