The engine family commonly called the LS series debuted in 1997. General Motors called it the Gen-III Small-Block, with the iron-block versions in trucks and the all-aluminum LS1 introduced in the then-new C5 Corvette. GM has continued to refer to its modern V-8 engine family as Gen III and Gen IV, but to the enthusiasts who quickly grasped the tremendous performance potential of the engines, every engine of the platform is nicknamed “LS.”

This engine is a 100% Brand New GM 5.3L that GM built for 2005-2009 Trucks and SUV’s. ATK went through the engine doing a camshaft and valve spring upgrade along with building it as a non AFM/DOD version of engine.  This engine will come with the valve covers and timing cover. This is a limited production an all-aluminum engine that is known for its extra-thick cylinder sleeves. For optimal Performance you will need headers, chassis dyno tune (required) and upgraded injectors.
