As you can see, increasing amperage and/or reducing kv increases torque. So, for a given amperage, the lower kv motor will have more torque.
FYI: you can also calculate HP without voltage and current:
Mechanical HP = torque X rpm / 5252

Would not torque and horsepower be equivalent in a rotating system? As torque is the turning force to overcome a load in a rotating system, so is horsepower a pulling force to overcome a load in a linear one. Since someone many years ago started using the value of horsepower to describe the force in a rotating system where torque should have been the standard, I don't think that in this instance they can be separated. I can gurantee that a vehicle with no rated horsepower, also generates no torque as well.
