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

I have a 2006 Ford F150 with the 5.4 Triton 3 valve, I am replacing all the timing system, and oil pump with a high volume pump, so I bought the ford racing M-6600-f46 pump. I was told that it can run this oil pan dry and mess up the engine. does anyone know anything about this?

What all will it take to swap a 2008 5.4 3 valve into a 1997 5.4 . 2 valve ..already know we have to change the intake and the fuel rail and possibly the computer.. Any thing would be helpful thank u

I have an 06 f250 superduty with the 5.4 3 valve can I change it to a 5.4 2 valve
