More air and fuel equals more power, correct shruggy


You have to remember that on a fast rate of lift cam sometimes the lift has to be higher than the cam designer might want or need. He can't just square off the top of the lobe because the lifter would not be able to follow the profile without floating. He needs the extra lift from the lobe to "slow" the valve down so it can reverse direction and start closing without floating. This allows more dwell time at the maximum flow of your heads and hence more power.
