Built By Hand
Assembly of every LS7 engine is performed by hand by a dedicated team member at GM's new Performance Build Center . The engines are pushed through approximately 15 sub-assembly stations, where only the components and tools necessary to complete the station's task are on hand. Tools such as electric torque wrenches provide repeatable accuracy for the engine's precise tolerances, while the eyes of the specially trained team members provide intangible attention to detail.
Team members are engine-build specialists selected from GM's experimental engine lab, and they complete about 30 LS7 engines per day.
