Quite interesting!! Good article and it does hold some truth and merit! But, there are cam/head combos, that will produce good airflow VELOCITY for more effective power at lower rpms in some engine combos. Better burn, in cylinders, more midrange hp/torque so you won't buzz the engine as high to get an identical rate of velocity in the manifold/heads/cylinders. To do the latter you would need more port VOLUME (bigger ports) which rquires MORE engine rpm to be effective. Great for racing, not so good for "street/strip" which would lean towards a bit "wider" powerband.
