How much horsepower does a 2000 Chevy 2500 454 have?
In the 2000 Chevrolet Silverado 2500 with the 7.4-liter V8 (the 454 cubic inch engine), the engine is rated at about 290 horsepower.
That figure reflects SAE net horsepower for the era and is paired with roughly 410 lb-ft of torque, making the big-block V8 a torque-heavy powerplant designed for heavy-duty towing and payload work rather than blazing acceleration.
Engine details
The 7.4L Vortec 7400 is a big-block V8 used in GM’s heavy-duty trucks around the turn of the century. For the 1999–2000 Silverado 2500/2500HD line, GM listed SAE net horsepower at 290 hp and torque at about 410 lb-ft. This setup emphasizes low-end and mid-range torque to help with towing and hauling capability more than peak horsepower output.
Notes on the numbers
Horsepower ratings can vary slightly by source depending on how the measurement was performed (gross vs. net) and by the exact model year or drivetrain configuration. For the 2000 2500 with the 7.4L V8, the commonly cited figure is 290 hp (SAE net) and 410 lb-ft of torque. Real-world results can also be influenced by engine wear, altitude, emissions equipment, and other variables.
Performance context
Owners typically value the 7.4L V8 for its robust torque over outright horsepower. The engine’s strength helps with heavy-duty tasks such as towing trailers, hauling loads, and maintaining highway speeds when carrying heavy payloads. While not the briskest accelerating option in the fleet, the power delivery is well-suited to work-truck duties common for a 3/4-ton or heavier pickup from that era.
Summary
The 2000 Chevrolet Silverado 2500 with the 7.4-liter 454 V8 is commonly rated at 290 horsepower (SAE net) and about 410 lb-ft of torque. This combination underscores torque-oriented performance ideal for towing and hauling, aligning with the truck’s heavy-duty design and use case. For exact figures on a specific vehicle, consult the build sheet or the engine’s label, as minor variations can exist by model year and configuration.
