Changing from a V-6 to a V-8 isn't a simple swap. The wiring and
computer will need to be replaced, as well as, springs, fuel supply etc.
This is further complicated if your Mustang is a 1996 model or newer.
Those cars are configured to take the 4.6L engine so to put a 5.0L
block in it would require changes to the motor mounts etc. My advice is
to rebuild the V-6 and if you have to have a V-8 then sell your current
car and buy a GT.
