Could we use '03 - '04 Mustang Cobra engine parts and supercharger on our TBird's 4.6? I'm guessing that it could be definatly done but, how much custom fabrication must be done and would our cast iron block be beefy enough? I ask because Ford used a cast iron block instead of aluminum to handle all the power better. Has anyone on here done this, or know someone who has done this? On wikipedia they were saying it was dynoing like 410-420 horse power from the factory!
