How much horsepower does a 2008 Ford f350 PowerStroke have?
The 2008 Ford F-350 Power Stroke diesel is rated at 350 horsepower.
In the 2008 model year, Ford introduced the 6.4-liter Power Stroke V8 turbodiesel for the Super Duty lineup. This engine is configured for heavy-duty work, delivering 350 hp and 650 lb-ft of torque, designed to handle towing and payload demands. The 6.4L powered the F-250, F-350, and F-450 through 2010, after which Ford transitioned to the 6.7L Power Stroke in 2011.
Engine specifications
Key technical details for the 6.4L Power Stroke in the 2008 F-350 are summarized below:
- Engine: 6.4-liter Power Stroke V8 turbodiesel
- Horsepower: 350 hp at 3,200 rpm
- Torque: 650 lb-ft at 1,600–2,600 rpm
- Model-year range: 2008–2010 for the 6.4L in the Ford Super Duty lineup
Notes: Factory ratings reflect the official specification for this engine. Real-world output can vary with drivetrain configuration, maintenance, and aftermarket modifications.
Context and impact
Why horsepower matters for a heavy-duty pickup: It influences how quickly the truck can accelerate under load, maintain highway speeds when towing, and climb grades with a trailer. The 6.4L Power Stroke’s substantial torque at relatively low engine speeds is particularly valuable for towing and payload capability in the 2008 F-Series Super Duty lineup.
Model-year context
The 6.4-liter Power Stroke used in the 2008–2010 Super Duty was later succeeded by the 6.7-liter Power Stroke in 2011, which offered improved output and efficiency in subsequent models. The 2008 model year is notable as the introduction year for this engine family within Ford’s heavy-duty range.
Summary
The 2008 Ford F-350 Power Stroke delivers 350 horsepower and 650 lb-ft of torque from a 6.4-liter V8 diesel, tuned for strong towing and payload performance. This engine period marked a transitional phase before Ford moved to the larger 6.7-liter Power Stroke in the following years.

How much horsepower does a 2008 6.4 Power Stroke have?
A stock 2008 6.4L Powerstroke engine produces 350 horsepower and 650 lb-ft of torque. With aftermarket performance parts, it is possible to significantly increase horsepower, with some modified versions reaching over 500 horsepower.
- Stock: The factory-rated output for the 2008 6.4L Powerstroke is 350 hp and 650 lb-ft of torque.
- Modified: The engine has significant potential for modifications. Owners have modified it to produce 500 horsepower or more through upgrades like a new turbo, injectors, and other performance parts.
Is the 2008 6.4 Power Stroke a good engine?
No, the 2008 6.4 Powerstroke is generally not considered a good or reliable engine due to a number of known issues. It was plagued with problems like a high-pressure fuel pump (HPFP) that could fail, cracked pistons, and a notoriously unreliable emissions system, especially the EGR cooler and DPF. These issues often resulted in expensive and catastrophic failures.
Common problems with the 6.4 Powerstroke
- Emissions system failures: The EGR cooler is prone to clogging and failure, which can lead to overheating and damage to the engine. The Diesel Particulate Filter (DPF) also clogs frequently.
- Weak internal components: Pistons are prone to cracking under pressure, and there have been issues with head gaskets and a lack of oil lubrication for the rocker arms.
- Fuel system problems: The high-pressure fuel pump (HPFP) is a weak point and can self-destruct, contaminating the entire fuel system with metal fragments and causing expensive damage to the injectors and other components.
- Cooling system issues: The engine is susceptible to overheating from multiple sources, including the common EGR and oil cooler failures, as well as a stock radiator that can leak.
- Other problems: Leaks from up-pipes and a potential for cylinder washing have also been reported.
What to know if you're considering a 6.4 Powerstroke
- Expect high maintenance costs: Because of these widespread problems, the engine requires diligent and often proactive maintenance to avoid major failures.
- Potential for catastrophic failure: Many failures are not minor fixes; they can be catastrophic and expensive to repair.
- Not recommended for the average owner: If you're not a "do-it-yourselfer" or don't have a large budget for repairs, this engine is likely not a good choice.
