HP DOES NOT EXIST per sa.

Torque is the only measure of rotational energy PERIOD!

HP is torque x RPM/5252.

Cam profile, head flow, CSA and engine volume (CID) can drastically effect where and when you make torque.

HP is only the ability to make torque a RPM.

A big head on a small engine will make lousy low speed torque but it will be able to support RPM so it makes HP at a higher RPM. The converse is true if you have a small head on a big engine, it will make gobbs of torque but the small head will not allow the engine to breath at higher RPM to make more HP.

Thats why 440's were always perceived as torquey engines. A good amount of cubic inches with a head better suited for 350-370" engine.

Class over
