4.8 motor to LS2 swap! Questions

[Sergio6.0]

I know this has probably been asked in the past but I have a question getting a real good deal on a TBSS LS2 complete engine 

I have a high mileage 4.8 in my 2004 silverado (single cab)
Found a lower mileage ls2 6.0 of a TBSS (complete) for a good deal , is it a direct fit or what else will I need to make it work? ( other than the Lingenfelter control module, from my understanding to make it work)

You can swap reluctor wheels instead of Lingenfelter box

Other mods will have to be done because they run the newer intake manifolds. So fuel rail hookups, MAP sensor wiring because they use a different MAP sensor. I'm sure some other minor odds and ends and of course the crank/cam trigger difference that can use the box or swap reluctors and cam gear.

 

Then it's mainly all tuning to make it function correctly with all the different parts.
