Super nice 5th Gen in for a complete make over!

We started this thing off by sending in the manifold and throttle body off to Gwatney Performance Innovation for a port job

Next we got a set of Texas Speed Brawler series heads set up for this bad girl.
Paired with a new set of long-tube header’s to help the breathing. Finished it off with a cam package from Texas speed! Lastly to keep drivability great we gave our friends over at Circle D Specialties a call and got it hooked up with a 3,200 stall convertor!

After dialing it in with a Next Level tune this thing laid down over 515whp while maintaining great drive ability!
