We just finished up a 5.7l 09 Dodge Challenger. We went ahead and built a 393 stroker for it, ported the heads, built transmission, torque converter, and built a custom fuel system for it. These baseline pulls are only on 5lbs of boost. Once the customer breaks in the motor he will be back for a pulley upgrade!:devil: Stock she dyno'd right at 300hp and 332tq. On 5lbs of boost she made 454rwhp and 475rwtq. At 3300 rpms she went from 290rwtq to 452rwtq. She makes great low end power. Will post dyno #'s once we put 15lbs of boost to her!
