      DESCRIPTION: We bored and stroked a 6.0 liter Powerstroke to a 6.3 liter making it 383 cu.in. More displacement resulted in dramatic gains in horsepower and torque! The entire rotating assembly has been Blue Printed and Balanced and Dyno tested with results. We stroked our 2004 F-250 utility truck with no upgrades, just simply a stock configuration.

       

      STOCK: 6.0 f-250
      270 HP @ 3300 rpm (at the wheels)
      485 ft lbs of torque @ 2000 rpm (at the wheels)
       

       

      RESULTS:

      6.3 “ PowerStroker’R”
      446 HP @ 3125 rpm (at the wheels)
      850 ft-lb of torque @ 2670 rpm (at the wheels)

       

      The “6.3 Powerstroke’R” gained 176 horses and 365 ft. lbs of torque! 

      These dramatic power gains are based on No modifications to the stock 2004 F-250. With a 2.5 inch exhaust. Any mods that anyone does to this platform will increase the HP and torque even more.
