Yukon Ok.
If you go with a 5.4 do make sure it has been remanufactured properly. Unfortunately the 5.4 although it is a good engine, does have issues with cam phasers. I do think Ford Resolved the spark plug ejection issue.
Cam phasers are 3 valve motors if I remember correctly.


To the PO. Just send it and get a chevy. I feel your pain with the ford modular motors, I have owned several and I feel like every one if them was junk.

I hate the 5.4l. Have one in an expedition owned since new. Cam phasers, bent valve, galled cam lobe. Sounds like a diesel starting. I'd do the cam phaser lockout if doing it again.

Luckily it’s a 2v. It’s going to be hard to find a truck as nice for its age.

Ls swaps are cool, but unless you are working on one that is popular and maybe even offered in a pretty refined kit, it will be expensive and/or time consuming IMO. It's not the motor and trans, but all the little bits to finish it.

Another Option Possibly worth exploring would be the Supercharged 5.4 from the F150 HD's or F150 Lightnings. Wiring Harness issues but at least you can find wiring Harnesses.
