I can help on this *is happy that knows something useful*
OK, with a Mark VIII engine you can just swap it right in and use all the existing wires and computers in the truck as long as its a V-8 truck. You will just need to retune the computer for the larger injectors, pump (need larger pump), MAF and t-body.
The DOHC 4.6 has an IRMC because the heads and plenum have dual runners to help create low RPM torque but at 3200 RPM they open to allow all 16 runners to supply air.
All you need to do is eaither get an IRMC delete kit or remove the butterflies and weld the holes that the shaft went through. The reason for this is because the stock computer can not controll them and to swap the Lincoln computer and harness over will be a major PITA.
Now this swap is easier with a Mark VIII motor or a Mach1 motor from a Mach that had the auto trans. 98-04 Cobras and 5-speed Mach1s had an 8 bolt crank which means you would need to have a flex plate made to hook to an auto trans.
Hope this helps.

I've done the swap in a coil on plug Mustang, I reused the 2V harness and PCM. In my case I had to lengthen all 8 coil wires, TPS wire, Fuel rail pressure sensor wire, and repin the alt. connector.
4V swap requires the 4V or Bullitt alternator, coolant hoses, thermostat housing and an inlet tube to accomodate the dual blade TB.
A retune is a must, A/F and timing tables are way out of whack otherwise.
