When it comes to power, precision, and durability, few engines have achieved legendary status quite like the Chevrolet LSX engine. Born from Chevrolet Performance’s relentless pursuit of perfection, the LSX was designed to dominate both on the racetrack and the open road. It’s more than just an engine — it’s the ultimate blend of American muscle, modern engineering, and limitless performance potential.
At its core, the LSX engine is a product of innovation and strength. Unlike standard LS engines that use aluminum blocks, the LSX features a cast-iron block designed to withstand the stress of extreme horsepower and high boost levels. Reinforced with six-bolt main caps and forged internals, this engine was engineered to handle over 1,000 horsepower — making it the preferred choice for racers and tuners seeking uncompromising performance.
