Assuming your 4.7 has a 545rfe trans behind it I'll also guess it has a seperate TCM like the 03 5.7. So the only real difference that I remember is the 4.7 has a manual TB and the 5.7 has FBW. There are two types (03-05). The 03 having a manual throttle pedal and remote APPS and the 04-05 have the APPS intergrated into the pedal assembly. The 03 remote APPS is difficult to find. The 04-05 are available. The only real advantage of the remote APPS is if you wanted to use a a 45rh transmission that requires a TV cable which can be attached to the remote APPS. This arrangement is often used with retro rods using a early trans and g3 hemi.
