In short. For the 5.0 motor in the new mustang to break 450 torque it would have to exceed the BMEP of a formula one engine which is at ~220psi.
As it sits the 5.0 is already at 194 psi bmep which is very astounding and quite an accomplishment for ford. But this is not so good for the outlook of future NA modifications and power output.
BMEP = 150.8 x TORQUE (lb-ft) / DISPLACEMENT (ci)
PLUG IN SOME NUMBERS AND ENJOY
LS3 at 200 psi bmep (stock is 168psi)= 500 torque (Rather accurate here)
5.0 at 200 psi bmep (stock is 194psi)= 400 torque. At 450 torque the BMEP of the 5.0 would be at 224 psi.

Is anybody really trying to suggest that a smaller displacement motor, normally aspirated, has the potential to make more power than one with larger dispacement?
