Torque is applied power. Power can be anything that can be measured, light, electricity, heat it is a nominal term. On a side note in theoretical physics it is accepted that light can move or displaced weight. theoretical being the operative word here. They have not yet designed a metering that can measure light actually moving anything of substance. But men/women working in applied physics are still trying to prove the theory. I think that they eventually will but it has no bearing on how much power is too much or enough when it comes to traditional hotrods.
