I have searched left and right and can't seem to find a definitive answer as to whether you can swap a later 5.4 into our trucks. I know that the computer(s) would be different because 2009 and up 5.4s came with six speed transmissions, but I would think that I could swap over my intake, wiring, and PCM and continue running my four speed transmission. Can anyone confirm or deny? Any information would be greatly appreciated.
