Engine swap

The swap is very possible as the 96 still uses the same 4.6L mod motor block. Things to consider: You will need a complete engine, harness, computer, transmission, and drive shaft. You will also need a new K-member/motor mounts. If I remember correctly, the 3v is taller than the 2v that came in the '96's. Pick the headers/exhaust you like that fit your application. You will need a new transmission mount since the '96 used the T-5 and the 4.6L 3v should have at least a TR3650 (manual) or a 5R55S (auto). You're best bet is to find a high mileage 3v or a wrecked one. Then you can swap the parts off the 2005-2010 in to your 1996. Other options include the newer 5.0L Coyote motor which has also been swapped already. Engine swaps from other years are not the cheapest route typically.

I have a question what do I need to put a 96 4.6 motor in my 04v6 mustangmustang

I have a question, can I put a 5.0 in a 2002 with a 4.6 swap out the4.6, and put the 5.0 to the same tranny will that work?
