Gen 3 and Gen 4 LS Engine comparison part 1

This series takes a look at some of the overall differences seen between the generations of the LS. In this, we look at my 2000 Silverado 1500 with an LM7 and discuss what changed and stayed the same on my 2011 Suburban 1500 LC9.GMT-800 and GMT900 trucks, vans, and SUVs have the most popular engine to be used in everything from off-road, drag, drift, professional, amateur, street, and track racing. I am trying to talk to myself as an 18-year-old and inspire thought and give understanding to what is under the hood of that old Silverado or Sierra he was driving. possibilities are only limited by own effort you want to put into your truck. Included trucks of this series are Silverado, Sierra, Yukon, Escalade, Express, Savana, Tahoe, Avalanche, Envoy, Rainier, Trailblazer, Hummer H2 and H3, and more.
