will my 07.5' engine work in a 2011 truck

I have a beat up 2wd cclb with a lmm and am wondering if it will work in this 2011 dually 4x4.
If anybody knows.

Far too many differences to be worth attempting. Completely different fuel system just for starters.

Curious what happened to the 2011 LML engine?
