What kind of engine does a Chevy Silverado 3500 have?
The Silverado 3500 offers two primary engine options: a 6.6-liter gasoline V8 and a 6.6-liter Duramax turbo-diesel V8.
In recent model years, the gasoline V8 produces roughly 401 horsepower and 464 lb-ft of torque, while the Duramax diesel delivers about 445 horsepower and 910 lb-ft of torque. Availability and exact figures vary by year, cab/bed configuration, and drivetrain, with diesel typically favored for heavy hauling and towing and gasoline serving day-to-day driving needs.
Engine Options
The two main engine options are summarized below to compare power and capability.
- 6.6L V8 gasoline engine — Delivers around 401 horsepower and 464 lb-ft of torque, providing strong everyday performance and reliability for a heavy-duty work truck.
- 6.6L Duramax turbo-diesel V8 — Produces about 445 horsepower and 910 lb-ft of torque, favored for heavy towing, high torque at low speeds, and sustained payload capability.
Note: Exact outputs can vary with model year, cab/bed configuration, drivetrain, and emissions equipment. Always check the vehicle’s build sheet for precise figures.
Performance and towing considerations
For daily driving and lighter duties, the gasoline engine offers smooth operation and adequate power. For serious towing and payload tasks, the Duramax diesel delivers substantial torque that improves acceleration under load and hill-climb capability. The choice hinges on how the truck will be used most of the time.
Summary: The Chevy Silverado 3500 centers on two engine options—the 6.6L gasoline V8 and the 6.6L Duramax turbo-diesel V8—each with distinct power profiles and towing capabilities. Your selection should align with whether your priorities are everyday driving comfort or maximum hauling performance.
