Notching Shock Tower
RRS makes a shock tower notching kit to fit modular motors in classic 'Stangs. It is sold by National Parts Depot for $194.95.
That would be the first step to putting that motor in. If there is a mock up of the 4.6, it might help to get one of those as well. Then you can put the mock up in and begin to find solutions for all the other problems that will come up like manifolds or headers, hooking up a cooling system, Air conditioning, electrical, motor mounts, etc. Depending on the transmission used you may have to fabricate some parts like crossmembers, transmission mounts, kick down levers, vacuum lines. Don't forget the transmission and engine for a 4.6 will both be computer controlled and the computer has to be fit somewhere. You will have to get a new fuel sending unit with a return like on a 5.0 EFI conversion. You will also need a new electric fuel pump and that will have to be fitted somewhere. The driveshaft may present problems as well, but you could probably have one custom made.
