LS7 V8 Engine

---

Inside every Z06 is an LS7 aluminum-block 7.0 Liter V8 that produces a Society of Automotive Engineers-certified 505 hp and 470 lb.-ft. of torque. Hand-built at the GM Performance Build Center in Wixom, Mich., the LS7 engine contains a litany of racing-derived components, such as an eight-quart dry-sump lubrication system, titanium valves and connecting rods, forged-steel crankshaft with six-bolt main bearings, high-profile cam, and Computer Numerical Controlled (CNC) machined heads for better air/fuel flow. Even with its impressive performance, the engine does not incur a federal government gas-guzzler penalty.
