Re: 4.6 and/or 5.4
actually it will bolt almost right in, however I do know you will have to use solid motor mounts for the 5.4 as it will have absolutely no flex room at all, I do know as well that you will either have to fabricate your own upper and lower intakes for clearance or you will need to buy an after-market hood.
now a friend of mine personally built his own intake, but he does work for a d.o.d. engineering firm, don't expect that to be an easy task.
