Ls Models -

The family is primarily divided into two generations before transitioning to the newer Gen V "LT" series: :

: Brands like Holley and Summit Racing offer complete swap kits, including wiring harnesses , oil pans, and engine mounts to simplify installation.

: Blocks are available in both aluminum (lightweight for performance cars) and cast iron (highly durable for trucks and high-boost builds).

: Its compact size allows it to fit into nearly any engine bay, from classic muscle cars to small Japanese imports. Core Model Generations

Unlike modern overhead-cam engines, the LS utilizes an "old-school" (overhead valve) design.
