Introducing LSX: No Dream Is Too Extreme
Dream bigger. Because the new GM Performance Parts LSX takes the LS-series V8 to the ultimate extreme. Shaped from 50-plus years of V8 know-how and refined with the speed secrets of Warren "The Professor" Johnson, the LSX block was engineered to handle up to 2,500 horsepower, all for a price that will have the rest of the world wondering how we did it. Build your dream with LSX, available March 2007.
