This cast-iron block V8 engine does about 360 horsepower at 5,400 rpm in the Chevrolet Silverado HD and 380 lb-ft of torque at 4,200 rpm. That packs a decent punch,which is no surprise, seeing as the engine was made from Corvette’s and Camaro’s famous LS engines. If you want a 7,800-pound truck that can do zero to 60 in 6.5 seconds, you should get a 2017 Silverado 2500 HD. The LS-based configuration is also why it’s an easy engine to mod and swap, with many aftermarket parts.
There are two valves per cylinder with a compression ratio of 9.7:1, meaning a sacrifice of speed for power (horsepower in exchange for torque) — which makes sense for big vehicles. The cylinders also have a unique shape that improves air intake, allowing for more power and torque. Additionally, the L96 further improves efficiency and performance thanks to variable valve timing (VVT).
You’ll also notice fewer vibrations from an engine of this size. It has noise-dampening components and a superior motor mounting system that eliminates rattling the GM vehicle’s chassis. For instance, the exhaust manifold was designed to be quieter and insulate heat to reduce the engine’s overall temperature.
