The Duramax LBZ was first introduced in 2006 as a replacement for the LLY engine. The LBZ offered significantly more power but was only available until the middle of 2007 when it was replaced by the LMM.The primary reason for replacement was due to stricter emissions standards, as the LBZ was the final Duramax engine that did not require a diesel particulate filter (DPF). The DPF certainly makes the engine appear much cleaner as it prevents the large amounts of soot from going directly out the tailpipe, but there are also several drawbacks to the DPF. One such drawback is the backpressure which adds additional load to the engine as increases in backpressure make the engine work harder to get the air out of the cylinders. Another major drawback is the fuel economy penalty that is most notable when the DPF is being cleaned. The fact that the LBZ had the increase in power and the latest technology but without the DPF is a major reason for the engine’s popularity.6.6L Duramax LBZ Performance SpecsThe LBZ also offered a significant performance increase over the LLY that it replaced. The LBZ was able to achieve 360 hp at 3200 RPM, 50 horsepower more than what can be reached with the LLY. The peak torque for the LBZ is 650 lb-ft, reached at 1600 RPM, also a significant improvement over the 605 lb-ft that can be reached by the LLY. The 6.6 L engine, or 402.8 cubic inches, achieves this displacement using a bore of 4.06 inches along with a stroke of 3.90 inches.If it were not for the DPF regulations my belief is that the LBZ would have been produced for many more years!!! This Duramax does it all right. And it shows no check engine lights, no blow by, no glow plug issue, no leaks, no rust, no stored codes, no exhaust leak. This truck is solid and not tampered with!
