Nearly identical in performance and construction to the Camaro's manual transmission LS3 engine, the L99 engine (equipped in automatic transmission Camaro's) is 400hp with 410ft. lbs. of torque and is equipped with GM's fuel saving Active fuel management (AFM) technology. AFM enables the engine to cut off fuel to half of the cylinders in certain light load driving conditions, such as highway cruising, to reduce fuel consumption. Special lifters are used to deactivate the cylinders effectively turning the engine into a V4 (the remaining cylinders pump only air). the changeover from V8 to V4 is virtually imperceptible.

The L99 crate engine comes fully dressed with the 2010 Camaro oil pan, manifold assembly (including injectors, fuel rails and electronically controlled throttle), ignition coils, exhaust manifolds, balancer, water pump and 14" automatic flexplate.
