Torque gets you off the line, HP is for speed
Torque is also what is most likely to break your tires loose in hard cornering if you tab the throttle too soon.
High rev mutli-cam engines typically make their HP with smaller displacement, Though not always lighter than a higher displacement pushrod they are usually more compact. This allows the engine to be mounted closer to the firewall for weight distribution. Though front engine with a 6L V12 the new Ferrai 599 ha a 47:53 weight distribution

Additionally high rev engines typically have much taller axle ratios to get the power to the wheels.
