Chevy 6.0l vortec engine
The Chevy 6.0l vortec engine L96 is an engine produced by General Motors for use in its full-size heavy duty (HD) pickup trucks, vans, and SUVs. Displacing 6.0 liters in a V8 configuration, the L96 is part of the Vortec (Generation IV Small Block) engine family, which was replaced by the EcoTec3 (Generation V Small Block) engine family. The L96 is the last Vortec engine currently in use by GM, with the EcoTec3 engine family replacing the Vortec line in all other GM vehicles. Notably, the L96 is the same engine as the LC8, but the LC8 is modified to run on Compressed Natural Gas as well as gasoline.

Cylinder Block and Rotating Assembly: the engine block was developed with math-based tools and data acquired in GM’s racing programs, and provides a light, rigid foundation for an impressively smooth engine. Its deep-skirt design helps maximize strength and minimize vibration. The bulkheads accommodate six-bolt, cross-bolted main-bearing caps that limit crank flex and stiffen the engine’s structure. A structural oil pan further stiffens the powertrain. Along with the rigid block, the engine’s rotating assembly was designed for optimal strength and duration complemented by features designed to make the L96 quiet and smooth. The L96 6.0L also features a heavy-duty timing chain developed expressly for quiet operation. The chain, which connects the camshaft and crankshaft, is validated for 200,000 miles of operation and fitted with a leaf-spring-type dampener.
High-Flow Cylinder Heads and Valvetrain: the L96’s cylinder heads feature “cathedral”-shaped intake ports that promote exceptional airflow. They’re derived from the high-performance cylinder heads that were used on the “C5” Chevrolet Corvette Z06 and support great airflow at higher rpm for a broader horsepower band, along with strong, low-rpm torque. The intake ports that feed the combustion chambers, as well as the D-shaped exhaust ports, are designed for excellent high-rpm airflow.
Advanced Electronic Throttle Control: with ETC, there is no mechanical link between the accelerator pedal and the throttle body. A sensor at the pedal measures pedal angle and sends a signal to the engine control module (ECM), which in turn directs an electric motor to open the throttle at the appropriate rate and angle. The ETC system can deliver outstanding throttle response and greater reliability than a mechanical connection.
