Long Tube Headers, x pipe, and catless system





I thought I would share with you all my current build, to turn this dream car into a complete monster. I thought it was lacking a little punch, so I decided to "open" the breathing of the car. what do you think?


  • Ported heads
  • Long tube stainless headers
  • x pipe w/ cat less system (I think I am gonna keep stock mufflers)
  • Comp Cam Double valve springs, Viton valve seals, Chromoly push rods, light weight titanium retainers
  • custom billet catch can
  • Comp Billet Cams
  • 160 degree T stat
  • Comp Cams roller rocker trunion kit
  • NGK plugs
  • Fast 102 intake
  • Fast fuel rails
  • Nick Williams Throttle body
  • Comp Cams billet belt tensioner
Any thoughts? I wanted to keep it NA for the track but really get the most of of the motor without using forced induction. One thing that surprised me was the Dyno pulled 466 whp (536hp crank), which either indicates very little drive train loss, or being that they are hand built, that some motors will be a little more powerful than others. Anyways, I believe we should be in the 570 whp (650hp crank) area when finished with great track capabilities. I will post pics once I pick it up on Monday, along with new numbers from the Dyno.
