You would probably have to put the 07 computers in it for the performance. However you could probably run the 03 computers but you would still have the non interceptor performance

But my 03 is an interceptor also

The 03-11 interceptors used the same engine components so departments could take two bad cars regardless of year difference (between 03-11) and make one good car.

Ok cool I found an 07 with 87000 miles bc my 03 the spark plug pop out of the heads messing up the threads so was just making sure before I go buy the engine

I don't know if you are planning on boosting the horsepower but with stock heads it is a bad idea because they might not be able to handle it. Also be VERY careful when installing spark plugs as the aluminum the heads are made of is very soft and strips easily I would suggest using a torque wrench (they are cheaper than replacement heads or another engine) Best of luck.

The 03 and older had only 4 threads in the spark plug holes. A change was made later to fix that. Changing computers will cause it not to start due the chipped key being matched to the old computer. If you change the computer you will have to have a Ford dealership or a locksmith marry the ignition key to the computer. I would think the engines will swap, but the transmissions may or may not due to later electronic revisions.
