The 7.3L gas V8 and 6.7L Power Stroke diesel solve different heavy-duty problems. The gas engine prioritizes straightforward operation and strong payload potential, while the diesel delivers far more torque for demanding towing. Joe Cooper Ford of Shawnee currently lists 2026 Super Duty inventory with both gas and diesel powertrains, making this a practical comparison for local truck buyers.
TL;DR
- The 2026 7.3L gas V8 is rated at 430 hp and 485 lb-ft.
- The standard 6.7L Power Stroke diesel is rated at 475 hp and 1,050 lb-ft; the High Output version reaches 500 hp and 1,200 lb-ft.
- Choose gas for simpler ownership, shorter trips, and payload-sensitive work. Choose diesel when frequent heavy towing and low-rpm torque matter most.
- Towing ratings still depend on the exact F-250, F-350, or F-450 configuration.

7.3L Gas vs. 6.7L Power Stroke Specifications
| Powertrain | Horsepower | Torque | Best Use |
|---|---|---|---|
| 7.3L gas V8 | 430 hp | 485 lb-ft | Mixed work, payload-sensitive builds, shorter trips |
| 6.7L Power Stroke diesel | 475 hp | 1,050 lb-ft | Frequent heavy towing and long-distance hauling |
| 6.7L High Output Power Stroke diesel | 500 hp | 1,200 lb-ft | Maximum Super Duty towing capability in eligible configurations |
All three pair with Ford heavy-duty automatic transmissions, but the important difference is torque. The diesel's low-rpm torque gives it a major advantage when launching and maintaining speed with very heavy trailers.
Why Choose the 7.3L Gas V8?
The 7.3L gas V8 is a strong choice for drivers who need serious Super Duty capability but do not routinely tow at the top of the platform's ratings. Gas engines avoid diesel-specific systems such as DEF and diesel particulate filter regeneration, which can make them appealing for fleets with shorter routes, frequent starts and stops, or trucks that spend substantial time unloaded.
Because a gas powertrain is generally lighter than a comparable diesel configuration, some gas trucks can also offer an advantage in available payload. The exact payload still comes from the specific truck's certification and loading labels.
Why Choose the 6.7L Power Stroke?
The Power Stroke is built for sustained heavy work. The standard diesel produces 1,050 lb-ft of torque, while the High Output version reaches 1,200 lb-ft. That torque is especially valuable with large fifth-wheel campers, livestock trailers, equipment trailers, and commercial loads.
Ford also integrates diesel-specific towing support such as an exhaust brake on properly equipped Super Duty trucks. For drivers who tow long distances or climb grades under load, the diesel's torque and engine-braking capability can materially improve the towing experience.
Ownership and Maintenance Differences
The gas engine generally has fewer diesel-specific maintenance items. The Power Stroke adds DEF, diesel fuel filtration, water-separator service, and emissions-system considerations. That does not make diesel ownership a poor choice; it means the additional capability should match the work you actually perform.

Frequently Asked Questions
Is the 7.3L Ford gas V8 powerful enough for heavy towing?
Yes. The 7.3L gas V8 is a heavy-duty engine rated at 430 horsepower and 485 lb-ft of torque. Its actual towing rating depends on the truck configuration.
What is the difference between the standard and High Output 6.7L Power Stroke?
The standard 6.7L is rated at 475 horsepower and 1,050 lb-ft of torque. The High Output version is rated at 500 horsepower and 1,200 lb-ft.
Which Super Duty engine is better for short trips?
A gas engine can be a practical choice for shorter routes and frequent stop-and-go use because it does not rely on diesel aftertreatment operating patterns. Choose based on workload, annual mileage, towing frequency, and ownership priorities.
