The Chevy 6.0 liter small block engine is an eight-cylinder engine aligned in the V formation and is called the Vortec L96. As of 2015, it is used primarily in Chevy's heavy-duty trucks, vans and SUVs and is the last Vortec engine in use by Chevy.
The 6.0 liter has variable valve timing, which helps the engine optimize its performance and efficiency. The engine is noted for its good airflow, which is an improvement over previous engines. This is done through straightening and improving the airflow from the intake manifold to the cylinders. Another improvement was to minimize noise through a stronger engine mount and cradle, which helps reduce the vibrations in the chassis.
The engine's main assembly sites are in Romulus, Michigan and Silao, Mexico. The valve configuration of the engine is overhead with two valves per cylinder. Compression ratio is 9.7 to 1 and the firing order of the cylinders is 1, 8, 7, 2, 6, 5, 4, 3. Regular fuel is used in the majority of the vehicles with this engine, but Chevy and GMC offers two vehicles using E85 flex fuel, the Chevrolet Express and GMC Savannah. Horsepower from this engine varies from 322 to 360, and torque is 373 up to 382.
