The term "Horsepower" can't be measured! It must be calculated. Torque X RPM/ 5250. Has something to do with a horse lifting 33,000 lbs of weight over a period of time. Now the formula fussy about where the torque is at, Lots of torque at low rpm's very little hP. Not much torque at high rpm's lotsa hp. When your engine is turning hi rpms, iy's power is limited by the size of the intake port, which acts like a governor to limit airflow into the cylinder and a hot cam can't improve upon a small port. After looking at allot of dyno runs you can see the max torque drop in RPM as the displacement increases. Now add a blower and the torque increases as boost goes up. Thus more horsepower.. I think that;s why I like the 258 engines with aL-100 they'll turn 5k plus and make a fair amyt of hP.
