Does Chevy make a 3500 gas engine?
Gasoline option for the Silverado 3500HD
Details about the gasoline engine option are helpful for buyers prioritizing upfront cost and refueling convenience. The primary gasoline powerplant for the Silverado 3500HD is a big‑displacement V8 designed to deliver solid work capability without the complexity of a turbo diesel.
Gasoline engine details
- Engine: 6.6‑liter V8 gasoline
- Approximate output: around 401 horsepower and about 464 lb‑ft of torque
- Transmission: paired with a heavy‑duty automatic transmission
- Application: available on certain Silverado 3500HD configurations and model years
In practice, the gasoline 6.6L V8 provides strong everyday performance and easier fueling in markets with limited diesel availability, but it typically delivers lower maximum towing and payload figures than the diesel alternative under heavy loads.
Duramax diesel option for the Silverado 3500HD
For buyers who need maximum towing and payload capacity, the Duramax turbo diesel remains a core option in the Silverado 3500HD. The diesel variant is designed specifically for heavy hauls and long-distance work, with higher torque at low speeds.
Diesel engine details
- Engine: 6.6‑liter Duramax turbo diesel
- Approximate output: about 445 horsepower and 910 lb‑ft of torque
- Transmission: paired with a heavy‑duty automatic transmission
- Application: widely available across many Silverado 3500HD trims and model years
The diesel setup is favored for serious payloads and towing sustained over long periods, thanks to its high torque and efficiency under load. It does come with higher maintenance costs and typically higher initial price than the gas alternative.
How to compare and decide
Choosing between the gas and diesel options depends on your typical workload, fuel considerations, and ownership costs. The following factors are commonly weighed by buyers of the Silverado 3500HD:
- Payload and towing requirements
- Initial purchase price and fuel economy on the road
- Availability of fueling infrastructure and diesel maintenance considerations
- Maintenance intervals and long‑term reliability for heavy‑duty use
For buyers who frequently haul heavy loads or travel long distances with a trailer, the diesel generally offers better performance metrics. For those who mostly use the truck for daily driving or lighter towing, the gasoline option can be more economical and convenient.
What to check before you buy
To ensure you are getting the right powertrain for your needs, verify the following with your dealer or sales consultant.
- Confirm the model year and trim level to see which engines are offered in that configuration.
- Check the window sticker for the exact engine, transmission, and axle specification.
- Ask about towing/payload ratings for the specific engine and axle combination you’re considering.
- Inquire about maintenance plans and fuel availability in your region.
Concluding note: The Silverado 3500HD provides a gasoline 6.6L V8 option and a Duramax 6.6L turbo diesel option in many model years. There isn’t a standalone “3500 gas engine” line, but the gasoline option is a legitimate configuration for buyers who prefer gas power. Always verify current offerings with a Chevrolet dealer for your locale.
Summary
Chevrolet does offer a gasoline engine option for the Silverado 3500HD, but there is no separate “3500 gas engine” model. The two main powertrains are a 6.6‑liter V8 gasoline engine and a 6.6‑liter Duramax turbo diesel, with availability varying by year and trim. Consider payload, towing needs, and total cost of ownership when choosing between gas and diesel, and confirm exact specs with a local dealer before purchasing.
