That is a great run down. Now someone said need Torque Converter off 5.9 is that true? Also what what about the PCM. I think it is in Pass firewall. Do I need that off 5.9 truck?
Torque converter is a no. 96+ use the same unit for both 5.2 and 5.9.
Thank you for bringing up the pcm, I had a brainfart while posting the year stuff above and forgot to include it. PCM is in fact programmed differently between the 2. They have different fuel trims on account of displacement and marginally different cam profiles. 5.2 pcm will run a 5.9 a tad lean and vice versa so you will need the correct year/engine/trans combo pcm.
Ok found a 5.9 out of '01 160,000 miles 6 month warranty. But will injectors and fule rail off my 5.2 work or I need 96-99 5.8 injectors? Its out of a 2500 van, still work.
Yep injectors and fuel rail from the 5.2 will work. 5.2/5.9 use the same rail/injectors, only difference is based on year. 94-99 use EV1 connector, black injectors. 00-02 use the red, pencil, EV6/USCAR style.
Easiest way is going to be using the Ford fuel line disconnect tool to disconnect the fuel line before the rails and then swap over the intake manifold/rail/injectors as a whole unit. This is ALSO the perfect time to do the plenum fix and port the runners should you so desire to.
