I have an 2005 1500 gmc crew cab with 5.3 in it an I'm
Wanting to put a 2013 5.3 motor in my truck was wondering
What all I'd have to do get it to work

58x to 24x conversion box or pull the engine apart to change the reluctor wheel, change timing gear, move knock sensors
You would either run your intake and tb or use an X link to control the new tb with your harness
Possibly a dod delete and cam swap with new timing cover and valley cover

To me it costs far too much for the swap to be worth it.

It's easier to just cam the old motor and make more power.
