I know I've seen this discussed somewhere on here but now I can't seem to find the thread. Will a Kenne Bell kit for a 5.4 bolt right up to a 4.6 and what modifications are needed?

 

If the kit includes an intake manifold, it won't fit because the 5.4 blockis substantially wider. If ot bolts to the existing manifold, then maybe but the displacement and speed parameters are going to be all wrong for the 4.6.
