Built with top level performance in mind, Pacific Performance Engineering's Stage 6 will handle sled pulling and drag racing.

Thanks to the Valve Body Re-calibration Kit (re-calibration kit does not change shift points, only increases clutch holding power), Converter Flow Valve, upgraded C1, C2, C3 and C4 clutches and kolene steels, the Stage 6 will hold up to 1,500+ horsepower at the crank (1100 rwhp) and 2,000+ ft. lbs. of torque.
