Couldn't agree more with this statement although 1/4 of the time may be conservative. LOL
The only thing I would add about the whole "big cam going slow" statement is this.
If the engine were correctly cammed or even slightly undercammed the entire combo has a much greater chance of performing better. Not to mention that most inexperienced people simply cannot tune an overcammed engine.
Over cam--Your entire car combo better be well executed
Under cam--Your entire car combo can have many "misses" and still work well.
