A shame…. You were getting really funny with the pictures.
What your looking at is the HP @ peak and calling it the final factor in the decision. This is short selling the stroker. Ultimately, the bore size is the limitation on HP being able to be made. The stroke increase is for torque. Since your increasing the cubic inches, the possibility of more HP is possible even with the same bore size but yet still limited because of it.
Being that stroke is increase to make more torque, the HP will increase in all areas as long as the torque is superior against the stock or lesser stroke engine. This is where your he win is.
Unless the engine size becomes vastly different, the change in rpm peak to peak is small. You listed this yourself and claimed it was huge until you seen different but still called the 300 rpm change large, which then called for a gear ratio and/or tire size change. This would inky be needed in the maximizing of the vehicle in a drag race.
