### The Evolution of the LS2 V8 Engine The LS2 V8 engine, released in 2005, marked a significant milestone in the evolution of General Motors' (GM) small-block architecture. Building on a lineage started in 1955, the LS2 retained key characteristics of the LS1, such as the pushrod design and 4.4-inch bore distance, while introducing refinements and performance improvements. ### Performance Enhancements The LS2 V8 engine boasted a 6.0-liter displacement, pumping out 400 horsepower and 400 lb-ft of torque, respectively. This represented a 50-hp and 40-lb-ft increase over the Corvette C5's LS1. The engine's performance was further enhanced by revised components, including the cylinder block, cam profile, exhaust manifold, ignition system, pistons, and oil pan. ### Technological Advancements The LS2 engine also featured an electronic throttle control and, in some versions, a cylinder-deactivation system. The latter allowed for fuel efficiency savings when power demand was low. These technological advancements showcased GM's ...
