* 6.0L Power Stroke V8 Turbo Diesel: This engine produced approximately 570 lb-ft of torque. (This is the most common high-torque option.)
* 5.4L V8: This gasoline engine produced around 350 lb-ft of torque.
* 6.8L V10: This gasoline engine produced around 450 lb-ft of torque.
Therefore, there's no single answer. You need to know which engine is in the specific 2008 F-250 Super Duty you're interested in to determine the torque. The information should be on the vehicle's sticker or in the owner's manual.
