I currently have a 4.6 2v with a s475 with a fully built 4rw70 in my 2001 Bullitt Mustang but messed up a rod so looking to start a new build. I don't want to keep my 4.6 for the power I want to achieve, so been wanting to do a 5.4 2v out of a lightning. I am curious on what parts I can and cannot use. My cams, fuel rails, headers, motor wire harness, and if my 4rw70 will bolt right up? Also if there are other post with similar swaps please let me know. Any information appreciated.
