can you replace a 2006 3 valve 5.4, with a 2 valve 5.4
Not without a lot of retrofitting.
Maybe but you won't pass smog check and I doubt the computer is compatible with the older engine.
You'll probably have pcm ecm issues, plug the smog test situation.
can you swap the pcm out of the 2valve donor car
Can I use a 2000 f150 5.4 2 velve and put it in a 2007 Ford F-150 5.4 3 velve truck or what do I have to change to make it work
