Default HP and torque relationship in a light car

An engine build can be tailored to have a lot of torque or a lot of HP. There are always trade offs. Typically high HP would be made at higher RPMs and less driveability.

What do the engine builders have to say on the subject?

In a light weight Cobra, would you aim for HP and torque numbers to be similar or would you push for torque to be much higher than HP.

For example in a street driven Cobra would you prefer;
520 hp at 6000rpm and 540 torque at 4500rpm or
450 hp at 5200rpm and 570 torque at 4500rpm.

What is your logic behind your opinion?
