I need to know the specs of my 1986 ford f350 dually, 6.9L diesel. Need to know horsepower, weight, payload capacity, and dimensions.Any help would be appreciated.

 

Your GVW whould be on the federal sticker on the drivers door post. It should be 10,000 GVW, your truck should weigh empty around 5,500. It is best to weigh it at a certified scale. Your horse power is around 150 or 170 depending on which 6.9 you have. There should be a sticker on the right valve cover telling your the rating of the motor.
