Horsepower is often associated with speed but in fact, it represents the amount of work an engine can do over a set period of time. Torque is a measurement of twisting force and applies to the rotational movement of a moving part such as an axle. The higher the horsepower or torque – the more power or force that is generated.
Engine displacement is normally stated in cubic centimeters or CCs. It is defined as the total volume of air/fuel mixture an engine can draw in during one complete engine cycle. L-head engines quite often have more CCs than an OHV (overhead valve) engine but the OHV’s more efficient design actually produces more torque.
