Most of us are aware of the tendency of overhead cam engines to have less torque down low and make their horse power higher up in the RPM range, and that pushrod engines will make more torque down low and make their horse power lower in the rpm range.

What I am wondering is WHY?

How does cam placement affect these characteristics?
