There isn't a lot out for the Eagle motors, hard to tune as well. The 392 cams go in easy and make some decent gains, but nothing crazy. Forced induction or Nitrous is the only way to make good power. My buddy has a Challenger 5.7 with heads and a cam and all the other stuff and made 369 to the wheels, from 310 or so stock. It was a good 4-5 grand worth of parts and tuning though. Blowers can be around 5K too, and make over 400rwhp easy.
