Find Your 6.7 Power Stroke’s Factory Output

The factory 6.7L Power Stroke ranges from 390 horsepower in its original 2011 calibration to 500 horsepower in the High-Output engine. For 2023–2026 pickups, the rating can be either 475 hp or 500 hp because Ford offered standard-output and High-Output versions.

These ratings cover U.S.-market F-250, F-350 and F-450 pickups. Chassis-cab and F-650/F-750 calibrations can be lower even when the engine badge still says 6.7L Power Stroke.

Factory Horsepower And Torque By Model Year

Model year	Factory horsepower	Factory torque	Notes
2011, original calibration	390 hp @ 2,800 rpm	735 lb-ft @ 1,600 rpm	Launch rating
2011, updated calibration	400 hp @ 2,800 rpm	800 lb-ft @ 1,600 rpm	Ford-offered PCM update
2012–2014	400 hp @ 2,800 rpm	800 lb-ft @ 1,600 rpm	Standard pickup rating
2015–2016	440 hp @ 2,800 rpm	860 lb-ft @ 1,600 rpm	Larger single VGT turbo and other revisions
2017	440 hp @ 2,800 rpm	925 lb-ft @ 1,800 rpm	Same peak horsepower, more torque
2018–2019	450 hp @ 2,800 rpm	935 lb-ft @ 1,800 rpm	Increase of 10 hp and 10 lb-ft
2020–2022	475 hp @ 2,600 rpm	1,050 lb-ft @ 1,600 rpm	Third-generation engine and 10-speed automatic
2023–2026 standard output	475 hp @ 2,600 rpm	1,050 lb-ft @ 1,600 rpm	Offered alongside the HO engine
2023–2026 High Output	500 hp @ 2,600 rpm	1,200 lb-ft @ 1,600 rpm	Optional HO version
2027 High Output	500 hp @ 2,600 rpm	1,200 lb-ft @ 1,600 rpm	Only 6.7L diesel listed for pickups

Ford’s 2012 pickup specifications list the 6.7L at 400 hp and 800 lb-ft, confirming the early post-update rating (2012 Super Duty technical specifications). The original 2011 trucks launched at 390 hp and 735 lb-ft before Ford made a 400-hp/800-lb-ft PCM reflash available (6.7L model-year changes).

Ford’s 2015 Super Duty technical specifications show the next increase: 440 hp at 2,800 rpm and 860 lb-ft at 1,600 rpm. The 2017 Super Duty brochure lists 440 hp and 925 lb-ft, while the 2018 brochure lists 450 hp and 935 lb-ft.

For 2020, pickup output rose to 475 hp and 1,050 lb-ft. Ford’s 2025 technical specifications and 2026 pickup specifications list both later versions: 475 hp and 1,050 lb-ft for the standard engine, or 500 hp and 1,200 lb-ft for the HO.

For 2027, Ford’s pickup specifications list the 500-hp High-Output engine as the only 6.7L diesel, rated at 1,200 lb-ft (2027 Super Duty specifications). See what changed for the 2027 diesel lineup for the model-year details.

A 2011 Truck Can Have Two Factory Ratings

The 2011 model year is the main source of conflicting 6.7 Power Stroke horsepower figures. The engine debuted at 390 hp and 735 lb-ft, after which Ford released a calibration that raised it to 400 hp and 800 lb-ft. Model year alone therefore does not establish which software an early truck currently has.

For an exact answer on a 2011, have a Ford-capable scan tool or dealer identify its PCM calibration. A truck running an aftermarket programmer may no longer match either factory figure.

The calibration distinction matters when comparing trucks, reviewing scan data or returning a modified truck to stock. Calling every 2011 a 400-hp engine overlooks trucks that retained the original calibration; calling every one a 390-hp engine overlooks the Ford update.

Pickup Ratings Do Not Cover Every 6.7L Truck

An F-350 pickup and an F-350 chassis cab belong to different specification categories. Chassis-cab trucks and F-650/F-750 medium-duty models use application-specific calibrations rather than automatically receiving the pickup rating for the same model year.

For example, Ford offered the 2015 F-650/F-750 6.7L in 270-, 300- and 330-hp configurations. All three were well below the 440-hp pickup rating for that year (6.7L model-year changes).

Verify the VIN, body type and Ford specifications for the exact truck before ordering tuning or calibration-dependent powertrain parts. A compatible long block does not establish that the donor truck’s turbo, fuel hardware or PCM strategy matches the recipient.

The 475- and 500-hp figures for 2023–2026 also should not be assigned from model year alone. The truck must be identified as having the standard-output or High-Output engine. Badging, build information and the VIN-specific equipment record are more useful than a generic model-year listing.

Factory Horsepower Is Not Rear-Wheel Horsepower

Ford’s later specifications identify these figures as SAE engine ratings, not rear-wheel horsepower measured on a chassis dynamometer. A chassis dyno measures power after it passes through the transmission and driveline. Tire size, selected gear and the dyno’s correction method can also affect the displayed result.

Do not diagnose a truck as underpowered by comparing its wheel-horsepower result directly with the factory engine rating. The article’s table does not provide an expected driveline-loss percentage, so it cannot support a single calculated rear-wheel target.

Compare runs made on the same dyno with the same setup, then use scan data and fault codes to investigate a repeatable shortfall. If power falls off mainly under load, a restricted fuel filter is one possibility; follow the checks in signs of a blocked Power Stroke fuel filter rather than treating a low dyno number as proof.
