Good Cam Choice?

What happens AFTER peak torque? RPM goes up and so does horsepower. All while torque is going down.

The ability to increase power is limited. You increase cylinder pressure, increase RPM or both. Thats it.

The torque verses horsepower thing isn’t pointless. It matters.
It's pointless in that, unless You increase the level of torque past-peak or raise it, You will not see an improvement in Hp...it is mathematics...hence the flatter the curve, the faster the car..
