There may be features of the SHO that make it a better choice than the F200, and it is tempting to believe that bigger (displacement and cylinder count) must be better. But the physics say this. The feature of an engine that determines acceleration ("grunt") is torque. The feature that determines top speed is horsepower. Horsepower is calculated based on the torque and RPM of an engine at a given moment. The formula is: Horsepower = Torque (ft-lbs) x RPM / 5,252. So, regardless of whether it is a 4 cylinder or 6 cylinder, two engines that produce the same horsepower at the same RPM (e.g., 200 HP at 5,500 RPM) also produce the same torque. So, they will accelerate the same also.
