gen iii
The LS based small-block engine is the primary V8 used in General Motors' line of rear-wheel-drive cars and trucks. Introduced in January 1995, it is a "clean sheet" design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small block V8 that preceded it as the basis for GM small-block V8s. The basic LS variations use cast iron blocks, while performance editions are all aluminium with cast iron cylinder liners.
The LS small-block has been manufactured in three Generations – III, IV, and V – with preceding Generations I and II of modular GM small-block engines having been based on the Chevrolet small-block V8 originally released in 1954. GM recycled the "LT" designation beginning with the LS Generation V "LT1" in 2014.
Several versions of the LS were used in the Chevrolet Corvette, beginning with the LS1 in 1997 through the LS9 and others in 2013. Variants of the LT version of the GM small-block have been used since.
Most of the credit for this engine family must go to Ed Koerner, GM's Powertrain vice president of engineering operations at the time. He was a V8 design veteran and former National Hot Rod Association (NHRA) record holder in drag racing. Koerner had been the Chief Engineer for all the existing GM small-block V8 engines, and was put in charge of the "all new" Gen III LS1 V-8 development project, which would share no parts with previous engines. Design team-members included Alan Hayman, Jim Mazzola, Ron Sperry, Bill Compton, Brian Kaminski, Jon Lewis, Stan Turek, Don Weiderhold, and Dave Wandel.
The performance improvements in the LS-family V8s over the previous classic small block V8 family are several. The lower section of the block incorporates deep side skirts, along with 6-bolt cross-bolted main bearing caps. This fully boxes the crankshaft, creating a very strong and rigid structure that has been hot-rodded by enthusiasts to over 1,000-HP.
Although it is the same compact physical size as the classic small block V8, this block can accept a 4-inch stroke as an option in its stock form, due to the cam location being elevated slightly, compared to previous block designs. Also, the cam bearing journals are larger, to allow for a higher cam-lift profile than was previously possible. The stock aluminum heads can provide a high amount of air-flow, which previously could only be found in aftermarket race-performance heads.
The aluminum heads also incorporate steam vents to prevent gas pockets from building up in critical areas, and this is vital in allowing the coolant to manage heat build-up for high-performace applications. Such design features allow for a higher compression ratio with no fear of detonation. The thermostat has been located at a low position, which eliminates the possibility of a gas pocket preventing the thermostat from properly sensing the heat of the coolant.
Previous generations incorporated a coolant passage through the intake manifold to warm the incoming fuel-air mixture in very cold climates. However, modern fuel-injection techniques eliminate fuel atomization concerns under all conditions, so the LS family uses a dry intake manifold. This removes a common coolant leakage point, and also allows the incoming air to remain as cool as possible for better power production.
Great condition, comes mounted on a Global Defense Initiatives quick release mount. Included box and papers.
