Again do the math...

Tire diameter:

3.45
Camaro -
28.66" - 20" 112MPH = 4,530RPM (in 4th gear)

3.31
Mustang -
27.25" - 18" 112MPH = 5,940RPM (in 4th gear)
27.68" - 19" 112MPH = 5,940RPM (in 4th gear)

Huge difference. To get the Camaro in the same area:

4.10 = 5,384RPM (in 4th gear)
4.30 = 5,646RPM (in 4th gear)

Pretty clear picture.
