      There is quite a bit you can do to increase the performance of your FLEX 4.7L.
      1. Electric fan - Removing the clutch fan is a SOLID 10 RWHP gain
      2. CAMS -
        1. H/O camshafts. +20-25RWHP
        2. (H/O REGRINDS to choice of 206/212/218 and more)
        3. 2008-UP Cams - More aggressive than HO cams.
      3. Cold Air Intake. These are worth 10-12 HP... dont fall for any claims of more... Still worth while.
      4. Solid Lash adjusters - 1999-20013 3.7L & 4.7L - this is a great mod that is worth 15HP.
      5. TONE/RELUCTOR RINGS - 16-tooth or 32-tooth - For those who want to use a 2011 4.7L Short block on a 1999 4.7L vehicle (visa versa)
      6. SCAT H-BEAM RODS - (Rods direct bolt on to the 4.7L crank)
      7. ROSS PISTONS - (Intended to be used with our SCAT RODS
      8. 10:1cr - Cast piston rebuild kits - For those who want added performance without needing forged pistons and rods.
      9. ARP BOLTS - (Head studs, working on rod bolts)
      10. CNC PORTED HEADS - Our race ported heads with the right mods have made over 320RWHP!
      11. PORTED THROTTLE BODYS - 70mm is recommended for most applications -
      12. ALUMINUM INTAKE - Sullivan Intake manifold is the perfect intake for those who plan to run Nitrous, turbo or centrifugal superchargers.
      13. Custom Tuning - SCT or HP Tuner -
        1. 1999-2003 - We can tune almost everything from 4.7L, 3.7L 5.7L 6.1L 6.2L 6.4L... contact us and let us know what have.
      14. Superchips - 1999-Up 4.7L - This is a great mod for those who do not need custom tuning. Noticeable gains with several user features.
      This is just a short list... there are many other mods available.

      Feel free to contact me with any questions or concerns... there isn't much we haven't done with a 4.7L!

        I recently acquired a 2001 4.7l Dakota. The valve seat slipped around the valve a dinged the piston. it broke the valve guide on the opposite side of the head. I understand this requires a replacement head but is there any way to keep this from happening again? These engines are expensive to replace parts on. I am contemplating a 5.9l swap but am running into the whole VIN match for ECU, BCM, and Instrument cluster. Is there any way to bypass any of that with aftermarket?
