*sigh*. Assuming you have a slightly newer 4.6L (PI engine), there is NO difference between it and a 99-04 Mustang GT 4.6L 2V engine. All you will be able to use is the block and the heads, there is NO power gain from doing that. We can debate this all day long, but the 2V PI motor stang gets the same heads, all the castings are identical, its all homogenized and common engineering....thats why its called a MODULAR ENGINE.

the 2V 5.4L is great if you are towing stuff, but as far as performance, the 330CID 2V motor lacks the volumetric efficiency of the 4.6L.Whereas the 4.6L has a square bore and stroke, the 5.4L merely has an extended stroker without as increase to the bore of the block. Its your choice, just dont bitch about poor fuel economy.
