Looking on the Ford website tonight I found the performance specs. My truck has the 4.6L V-8 w 3.55 rear end ratio, this truck is rated to pull 6200 lbs. The engine peak HP is 231 @ 4750 rpm, the peak torque is 293 lb.-ft. @ 3500 rpm. Using the formula [Torque=(HP x 5252)/rated hp rpm ] I found that at peak hp the engine is cranking out 255 lb.-ft. torque, mathematically reversing the forumla I found that at peak torque the engine has 195 HP. I have yet to feel what this is, I have been real eay on the truck and I don't think I have even gone over 3000 rpm yet. I do know that you can do 75 mph and feel like you're doing 40mph. I'm surprised I haven't got a speeding ticket yet. At 55 mph I'm running about 1500 rpm, 70 mph just under 2000 rpm, 75 mph right at 2000 rpm. The last st. I must travel before I get out of town on the way home is a 25 mph speed limit and I dern near have to ride the break to be legal, it wants to go. The truck also has 4-wheel disc brakes standard.
