The Gen IV LS 6.0L and 6.2L V8s (2005–2017) brought serious street performance to GM’s trucks, SUVs, and sedans. Engines like the L76, L92, L96, and LS3 featured aluminum blocks (some iron for truck variants) and made up to 430 hp. Popular in vehicles like the G8 GT, Escalade, and Silverado HD, they offer a strong foundation for high-horsepower builds. Texas Speed & Performance offers proven cams, heads, and tuning to take these LS engines to the next level.
