im thinking about doing this swap because a have a spare 4.6 out of a crown vic, has anyone done this swap?

 

Search, the guys on power block did one. On here though aside from one guy spending a ton to put a 5.4 in his I think it's mostly 5.0L swaps.
They are wider then a 5.0L so you are gonna have to remove some stuff like a/c, move stuff around like battery and intake box.

I haven't personally done a 4.6 swap, but here's the site of a guy who has -- http://www.cardomain.com/ride/205226...er-regular-cab
