Chevy LS Performance Engine Packages
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 version introduced in the then-new C5 Corvette. A year later, the LS1 replaced the Gen II LT1 Small-Block in Camaros and Firebirds. The LS1 displaced 5.7 liters, similar to the previous-generation Small-Block, but the cubic-inch measurement differed slightly: 346 for the LS1 vs. the traditional 350 cubes.
In 1999, the Gen III platform spawned the higher-performance LS6 that was standard in the Corvette Z06. In 2005, the Gen IV branch of the LS family was born, differing from the Gen III with cast-in provisions for fuel saving cylinder deactivation, larger displacements and revised camshaft sensing. The performance versions of the Gen IV include the LS2, LS3, LS9 supercharged and LS7.
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 based on the platform is nicknamed "LS." The range of production engines from the LS platform iswide. On the truck side, iron-block engines have included 4.8L and 5.3L versions, as well as all-aluminum 6.0L and 6.2L premium engines. Car engines include 5.3L, 5.7L, 6.0L, 6.2L and 7.0L displacements, including some configured for front-wheel drive.
The home fabricator''s one-stop-shop to turnkey Vortec V8 engines.
For varying reasons GM rated the LM7 from 270HP to over 300HP for different years and applications. The LM7 was put in just about every 1/2 ton chassis of truck, van, & SUV for both Chevrolet and GMC from 1999 through the first part of 2007. Because of this and the booming economy of those times this is the MOST common of the GenIII V8 engine. Therefore it is the easiest to find with reasonable miles, in good clean condition, and adapt for your aftermarket project. Besides the smaller 4.8 that is simply not as desirable because of its C.I.D., the LM7 will generally be the cheapest!
Introduced in 2002, this is simply an LM7 with Flex-Fuel specific injectors. I see these from time to time, but there really is no reason to prefer an L59 over a standard LM7 for aftermarket applications. They really don''t have any price difference from my stand point. They can be easily identified by the more square injector plug and in later years by the rectangular metal fuel rails.
