A lot of the main dyno testing done was to evaluate the true gains of the different stages of "lump" head preparation with larger valves, etc... the other components like intakes and cam were just variables that can obviously be viewed as one cam and intake selection might show greater gains with a 1.84" valve head on a 292 instead of a 250, or the differences in a certain RPM range. So you really look at dyno reults as being more of a gain or loss with a certain combo and not just a number. Whether a dyno can truly measure the differences down to 2-3 HP between parts is always going to be challenged by those that have never been involved with that profession. But the bottom line is always going to be what makes the end user satisfied with what he/she chooses to use for their own personal driving habits and needs.
