Nice truck JPro, but I think you mean: 400hp/500lb-ft (pound/feet)
As in : pound feet: Torque is usually measured in Newton meters (Nm), or pound feet (lb-ft) – the latter not to be confused with foot pounds (ft-lb), as one ft-lb refers not to a twisting force, but to the amount of energy required to raise a 1lb weight by a distance of 1ft.
400 foot-pounds is the amount of energy required to lift 400 pounds exactly 1 foot...lots of weight lifters can do that, multiple reps too !!!
