Again my .02 on the cam is don't get too crazy. You will be surprised how well a "medium" size runs with your 408 planned combo. Depending on how you build the 408 I would be shocked if you didn't make at least 450 rwhp with a medium size cam that is super easy to tune. 450 hp at the wheels is over 500 at the crank. Are planning a manual or auto trans?
