the 4.2L makes 202-205 hp, but 255-260 ft/lbs of torque. The Mustang has a more aggressive tune, and you'll neet a programmer of chip to run the combination so with a proper tune, it could go up 7-15 +- more depending on octane, etc.
For all the trouble of swapping motors, computers and so fourth for those small gains wouldnt he be better off modding his current car?
