There is a defined range for rpm/ duration. You are operating above and beyond that range. Supercharging or turbocharging helps to stretch that range. It lets you "get away" with things that you can't with a N/A motor. In your case, you're "getting away" with alot. 5000+ lbs and almost in the tens,,,, you're doing good. Treat your engine to a little breathing. Go with at least 230 @050. You will be pleasantly suprised.



I'd love to run a 230 cam, however I'm still using the factory pcm and I wouldn't be able to get the engine to idle unless I two foot the brake and gas. Your correct about a 230. I engine dyno'd a few of these new Hemi's with 230-232 duration cams with excellent results. One motor made 700hp/735tq at 5000 rpm, non interfcooled, with 9 lbs of boost before belt slip ended the session.
