Unlimited Performance Potential for the Next Generation!
GM's LS engine family has revolutionized the performance world, taking it to unprecedented levels of power, durability and efficiency. It is fast becoming the engine of choice of enthusiasts from all walks of life: from street rods and muscle cars to drag strips, road courses and off-roading. Pace Performance offers a broad range of Chevrolet Performance Parts that are production-based as well as specialty LSX performance crate engine packages, from the LS1 engine that launched the revolution and the 638-hp supercharged LS9 from the Corvette ZR1, to hot LS376 engines tailored for carbureted applications in classic and race vehicles. Pace Performance also has engine building tools you need to install a modern LS engine in vintage sheet metal.
