Engine Options and Performance Metrics

The heart of the 2004 Silverado 2500 lies in its versatile engine choices, designed to meet a variety of towing and hauling needs. Chevrolet offered two primary engine configurations that year, each providing substantial power.

Duramax 6.6L Turbo Diesel V8

This engine is a legend in the diesel truck community. Producing an impressive 300 horsepower and a colossal 520 lb-ft of torque, the Duramax is built for serious work. Its turbocharging provides excellent responsiveness, especially when under load. Our analysis shows that the torque output is key to its exceptional towing and hauling capabilities, allowing it to confidently manage heavy trailers and payloads.

• Towing Capacity: Properly equipped, the 2500HD models with the Duramax could tow well over 10,000 pounds, with some configurations reaching up to 16,000 pounds. This makes it ideal for fifth-wheel trailers or large equipment.
• Fuel Economy: While diesel trucks are not known for fuel efficiency, the Duramax offered competitive mileage for its class. Expect figures in the mid-to-high teens on the highway under normal driving conditions.
• Durability: These engines are renowned for their long-term durability, often exceeding 300,000 miles with proper maintenance.

6.0L Vortec V8 Gas Engine

For those who prefer gasoline power, the 6.0L Vortec V8 was a strong contender. This engine delivered 300 horsepower and 360 lb-ft of torque. While it didn't match the torque of the diesel, it provided ample power for most tasks and often came at a lower initial cost. — Sam Darnold's Future: Franchise Tag?
