You'll need to change out all of the external dress items, but yes, as far as physically bolting in, it will fit. It'll be down on a power a little bit-the F4AE NPI heads on the '95 models are the worst modular 2V heads that were ever made, and are terribly restrictive. The F5AE NPI heads used on the '96-'99 models are far better.

Thanks, what about a newer 4.6, would that be an easy swap or would it be best to stick to 96-99,.

'96-'99 would be the easiest. But, you have to be careful of some of the '99 4.6L's-the Mustang got PI heads in '99,so the intake from your truck won't match the ports on the PI heads, and the car intake won't match anything on your truck.. You could get a PI head 2001-2007 4.6L 2V from an F150 or an Econoline complete with intake manifold and swap it in. You would get a slight power gain that way, although there will be some swapping of parts between your stock engine and the replacement for everything to match perfectly.
