the current 3.4L engines usually are projected to produce power to the highest rev possible. With this kind of displacement is useless to build a 3.4L engine mid-low revlimit if however won't develope a lot of torque.
The 458 GT is powered by a modified F142 set to reach max power in a lower revlimit than the road/gt3 version, with the aim to maximize the availabe torque. For this reason, even restricted, the engine developes around 520-540Nm with a revlimit under 6500! (the gt3 version revlimit is around 8000rpm)
