What kind of engine does a F-350 have?
The Ford F-350 Super Duty is typically equipped with one of two main engine families: a gasoline V8 and a turbocharged diesel V8. In today’s lineup, the focus is on a 7.3-liter gasoline V8 and a 6.7-liter Power Stroke diesel V8, with older configurations offering additional options depending on model year.
Current engine options for the F-350
Two powertrains dominate the modern F-350 lineup, tailored for heavy towing and work-terrain use. The following sections summarize what you’re most likely to encounter on newer models.
Gasoline option: 7.3-liter V8 “Godzilla”
- 7.3-liter V8 gasoline engine — naturally aspirated, designed for durability and strong mid-range torque; typically paired with a 10-speed automatic transmission.
In recent years, this engine has been a primary gasoline alternative to the diesel option, delivering robust power for everyday towing and payload tasks while avoiding diesel-specific maintenance considerations.
Diesel option: 6.7-liter Power Stroke V8 turbo diesel
- 6.7-liter Power Stroke V8 turbo diesel — turbocharged with very high torque output; paired with a 10-speed automatic transmission and commonly chosen for heavy towing and long-haul work.
Diesel versions are favored for their torque-rich performance at low rpm, which translates to excellent towing capability and sustained pulling power, especially under load.
Historical and other options
Earlier model years offered additional gasoline and diesel engines, though some have been phased out as Ford updates the lineup. The following notes cover typical historical options you might encounter when researching older F-350 trucks.
Past gasoline engines
- 6.2-liter V8 gasoline engine — used on older Super Duty models prior to the current two-engine focus.
- 7.3-liter V8 gasoline engine (earlier iterations) — the Godzilla 7.3L design has evolved over time and appeared in several prior configurations.
These gasoline options provided alternatives to the diesels in earlier generations, with different torque curves and fuel-economy profiles.
Past diesel options
- 6.0-liter Power Stroke diesel — an older diesel option that appeared on earlier Super Duty trucks before the current Power Stroke lineup.
Today’s F-350 diesel option centers on the 6.7-liter Power Stroke, which has become the standard for high-torque, heavy-duty towing and payload performance.
What matters for buyers
Choosing between gasoline and diesel depends on how you plan to use the truck. Diesel engines typically offer higher torque for heavy towing and sustained work, better fuel efficiency under load, and longer endurance for frequent heavy-duty use, though with higher upfront cost and maintenance considerations. Gasoline engines often come with lower purchase prices and simpler maintenance, but provide less torque at low rpm compared with modern diesels.
Summary
In today’s F-350 lineup, the two primary modern engine choices are a 7.3-liter gasoline V8 and a 6.7-liter Power Stroke turbo diesel V8. Older model years also offered other gasoline and diesel engines, but the current emphasis centers on these two powertrains to address a wide range of towing, payload, and work-duty needs. Always verify the exact engine, output, and transmission pairing for your specific model year and trim.
