LS GM 5.3 LMG 2011/16 COMPLETE CUTOUT LONG ENGINE NO ECU
The LMG engine is a 5.3L Gen. IV iron-block engine used in GM trucks and SUVs between 2007 and 2014. For marketing purposes, it was also known as the Vortec 5300.
Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era.
These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.
