5.4 to 4.6 engine swap

I have a 2000 f150 5.4 4x4 Lariat. the motor is shot. Can I put in a 4.6 in it without any mods? If so, what mods am I looking at?

Your Y pipe will be too wide to connect to the manifolds, can't think of any other major issues off hand.

5.4 to 4.6 engine swap

Thanks man. I was told by a friend but he didn't know for sure that the torque converter had to stay with the engine. Do you know anything on that?
