The LS2 engine is a 6.0-liter V8 introduced by General Motors in 2005 as part of the Generation IV small-block family. It was the successor to the LS1 and quickly gained recognition for its balance of power and refinement. Featuring an aluminum block and heads, the LS2 delivered 400 horsepower and 400 lb-ft of torque in stock trim. Its 10.9:1 compression ratio and improved internals provided both strength and efficiency, making it suitable for performance cars like the Corvette C6, GTO, and CTS-V. Thanks to its durability and widespread availability, the LS2 remains a popular option for enthusiasts looking for a reliable performance base that can be enhanced through modifications such as cam upgrades, forced induction, and tuning.
