I was looking over my two dyno graphs on my truck and I was wondering if the overlap on a given cam determine where the peak HP falls in the RPM band?

For example:
220/220 .56X/.56X 114+4 -8* of overlap
the HP started to fall off at 5600ish, peak HP of 303

222/224 .56X/.56X 112+2 -1* of overlap
the HP started to drop off at 6300ish, peak HP of 316

I think there is more to it than overlap,but its also dependant on other supporting mods.One thing i have learned is....same cam same year model truck with same mods,one will make more power than the other.Ive also noticed that the older cams seem to make more power and are more dependable....just my 2 cents

Yep, i understand all trucks are different, but for the example i listed both dyno numbers were from my truck, only differences being cam.

My tranny is doing fine, the truck only has 43k on it ... My truck get exercised everytime i drive it... That includes a regular shift point of 6300, track shift point of 6600, and the occasional 7000 when i am feeling stupid...
