Swap '99 5.4 to 3V 5.4?
My apologies if this has been covered, but the only threads I could find were people with 97/98 trucks wanting to swap to newer motors, and I know the PCM in the '99 is different.
I have a slight rod knock in my motor (212K-miles), and I'm gathering info for what is most likely inevitable, an engine swap.
Can anyone point me in the right direction to research what's involved, and if I even want to consider a late-model motor in my '99? (Or just post right here, of course.) Anything detailing a step-by-step would be awesome, as well.
Thanks.

All depends on how much money you want to sink into it. No matter how you look at it, it is not going to be cheap. There is a possibility that you could find an engine in truck that has been totaled. If you go that route I would make sure that the engine does run and runs smoothly before you consider such and option and of course check the mileage. Your safest bet though I think would be to go to http://www.motorcraft.com/catalog.do and check out what you can get there. There are remanufactured engines for sale there. You can even get remanufactured lightning engines. 
Any parts you may need would most likely be there as well.

The 5.4 3V engine and trans are run off the PCM's CAN network; you'll need the entire engine/trans harness and PCM from a 3V. You'll need to fabricate some kind of mechanical throttle linkage, since the 3V uses drive by wire. You'll have to address your fuel system as well, 2004+ F150s use electronic returnless fuel systems, your truck has a mechanical return system (I think).
It'll be a ton of work; you need to realistically ask yourself, is your truck worth it? You could end up buying all these parts and end up with a cobbled together ride that don't run right - if at all.
