i've been told a 351 lower intake will fit a 302 upper. does this mean i can run fuel injection (mainly the computer and throttle body) from a 302. i am going to assume the 4.6 computer and all the things that go along with won't work

It depends on which lower you are talking about. All the wiring forward of the front seats will need to be replaced with 94-95 Mustang wiring if you plan on going EFI. The dash harness wiring can come from a V6. The engine bay wiring has to be V8.
