It was the replacement for the LB7 V8 diesel engine, and was soon succeeded by the LBZ V8 diesel engine. While at the time, its 210–310 horsepower figure was decent, modern turbo-diesels can more than double the output. That’s why a LLY Duramax cold air intake is one of the top mods LLY owners.

Skip to contentThe Duramax LB7 V8 engine is one of the most popular diesel platforms today. The LB7 lasted from 2001–2004, and was the first Duramax engine GMC released. From the factory, the Duramax LB7 produced 235–300 horsepower and a whopping 500–520 lb-ft of torque. While these were substantial power figures in the early-2000s when GM created the engine, modern diesel V8s can easily double that output. That makes modding the LB7 a top priority for many owners.

Skip to contentThe LBZ succeeded the LLY engine in 2006 and was short lived, being replaced by the LMM in mid-2007. Some notable changes included an upgraded CP3 fuel pump for higher rail pressure and a lower compression ratio which eliminated issues with connecting rod failure in modified LLY’s. Part of the reason for the short life of the LBZ was emissions – the LBZ engine has an EGR system but lacks all of the other exhaust emissions components.The LBZ produced 360hp and 650lb-ft. of torque. It’s lack of emissions systems and easy power gains make it common to modify. While these power...…Skip to contentThe LBZ succeeded the LLY engine in 2006 and was short lived, being replaced by the LMM in mid-2007.

Skip to contentFirst released in 2001, the 8.1L Vortec – or Vortec 8100 – was one of the top platforms for GM truck owners for several years. Mostly used inside the Silverado/Sierra and Suburban/Yukon, the Vortec 8100 was a top engine for heavy duty trucks. It makes a healthy 320–340 horsepower and 440–455 lb-ft of torque depending on the model it’s in. Yet, it can still feel a little sluggish hauling around the heavy duty trucks and vans. Luckily, we have you covered when it comes to boosting power and increasing performance.
