torque comes from the weight of the rotating assembly. Thats why larger engines have more torque. remove weight, lose torque (gain top end HP). It spins quicker due to the quicker rate of achieving max torque (since it is lighter, it will achieve max torque faster).

these principals do not apply on vehicles with forced induction though.
