The 4.6 is wider than a Boss 429 so it won't fit with shock towers. Also as cool as they are they are small (281 cu in). I'd much rather swap a 5.0 HO in and it's almost bolt-in. With stock suspension their will be some issues. The late model 5.0 has a double hump oil pan that won't fit but switching to a 289/302 pan is easy. The 5.0 has the dipstick in the oil pan but the timing cover can be drilled to put it in the same location as the 289/302. The 5.0 also has a serpentine belt system which spins the water pump opposite of the original 289/302 and is designed for a cross flow radiator so the inlet/outlet are on opposite sides. Not a big deal but will have to be dealt with. Their are aftermarket wiring and computers to plug the late model EFI into a classic without much pain. You couls use a T5 or AOD also and get overdrive.

Thanks for the info that site you posted looks like it has some great info. The 5.0 swap looks to be pretty common after Ive done a little google research. I will probably end up going that route.

it makes the most sense. the 5.0 is basically the same as the 289/302's that came in the classic Mustang. The aftermarket for the 5.0 is huge and they can make big power.
