Do you plan to use the blower setup or go turbo?
The 5.4 has a taller deck height then the 4.6. In order to put all of the blower equipment on the 5.4 would either require a full GT-500/FGT heads, intake, etc, swap.
Or
My 5.4 swap kit that I fabricate and put together that allows the transition of all your old parts to be used on a 5.4 DOHC.
details on this 5.4 swap kit?
Still for sale?
where are you located? im interested.
