hey guys i was wondering if the 4.6 2v can be swapped for the 01-03 5.4 2v?
or swap for the 04-07 5.4 2v? which would be a better option.
the 4.6 v3 is not an option for me since there is nothing aftermarket for it besides air intake and exhaust.

2001 - 2003
231 hp @ 4,750 rpm
293 lb-ft @ 3,500 rpm
260 hp @ 4,500 rpm
350 lb-ft @ 2,500 rpm

2004 -2007
231 hp @ 4,750 rpm
293 lb-ft @ 3,500 rpm
300 hp @ 5,000 rpm
365 lb-ft @ 3,750 rpm
5.4L 24v (3v per cylinder) is introduced.

 

Been done many of times. Use the search button and you'll find a well done how to.

 

99-03 5.4 2 valve is easy. 5.4 3 valve, forget it.
