LS Engine Swaps & Complete Dropouts
What Are LS Engine Swaps & Complete Dropout Engines?
Looking to inject some extra horsepower into your hot rod or muscle car, or thinking of revitalizing an older truck? At Bow Auto Parts, we specialize in supplying LS Engine Swaps & Complete Dropout Engines – ideal for do-it-yourself projects and performance enhancement!
LS Engine Swaps refer to the process of replacing your existing engine with a powerful LS engine. Developed by General Motors, LS engines are renowned for their efficiency, power, and compatibility with a wide range of vehicles. From muscle cars to mud trucks, LS engines can offer a significant performance boost and make your vehicle renewed.
Although LS engines are one of the more popular choices for swap projects, Bow Auto Parts also has other complete drop-out options such as Hemi, SRT, and Coyote engines. We include (when applicable and available) harness, ECU, O2 sensors, fuel pedal, and accessories such as alternator and AC compressor. See Our Engines!

LS Engine Swaps vs Replacement Engines
The primary difference between an engine swap and a replacement engine lies in their intended use:
Engine Swaps, such as LS swaps and Complete Dropout Engines, are intended for changing the type of engine in your vehicle, often for an upgrade or to modify a vehicle for specific purposes.
Replacement Engines, however, are intended to replace the existing engine with an identical one, typically due to the current engine’s failure or deterioration.
