The phrase refers to local automotive businesses specializing in the removal and replacement of existing engines with a General Motors LS series engine. These shops often offer a range of services, from basic engine swaps to complete vehicle modification and performance upgrades tailored to the specific application. An example would be a shop performing an LS swap into a classic car, a truck, or even a more modern sports car to improve power, reliability, or both.
The significance of locating such establishments stems from the widespread popularity of LS series engines due to their robust design, affordability, and readily available aftermarket support. The process enhances vehicle performance and offers improved power-to-weight ratio. Historically, engine swaps were less common due to complexity and compatibility issues. The LS engine’s design simplifies integration into various chassis, creating a dedicated market for specialized shops and mechanics.
