^ this is true, but the thing is, i would splurge to get the best cam that will be most efficent in the overall setup that he is going with, the cam that will make the most power given the specs of the motor. i know it will kinda take the project out of perspective becuase using expendsive cams arent most cost effective, but it will be effective on making the most out of what he is running....that is just my take on it.
i think bigger cams and the bigger exhaust with more dialing on the cam gears will be most efficent
