The LS4 engine is a high-performance 5.3-liter V8 produced by General Motors between 2004 and 2008, specifically engineered for front-wheel-drive vehicles. Unlike other LS engines, which are typically used in rear-wheel-drive setups, the LS4 was adapted with a shorter crankshaft and unique oil pan to fit transversely in the engine bay. It delivers 303–310 horsepower and 323 lb-ft of torque, featuring aluminum block and heads, coil-on-plug ignition, and a high-flow intake manifold.

The LS4 powered models like the Chevrolet Impala SS, Pontiac Grand Prix GXP, and Chevrolet Monte Carlo SS, offering a balance of traditional LS V8 performance in a more compact, front-drive configuration. It features an aluminum block and heads, a 10.0:1 compression ratio, and a 96 mm bore with 92 mm stroke. The engine uses overhead valves with 2 valves per cylinder, a hollow steel camshaft, and sequential fuel injection, paired with a 4-speed automatic transmission. Special design elements like a shortened crankshaft, remote water pump, and a baffled oil pan allow it to fit FWD layouts while maintaining performance and reliability.
