yes the enegines are most likely 2 different types of the engine so not all the same parts will be on the engine as the other one. tho the switch is possible but make sure you transfer the computer with the engine because it will mostly likely not run at its full capacity with out it.

what size are the engines?

there is a couple types of v6 models that you will find and depending on the year the engine will have new this or old that for computer hardware in it. the sierra comes with a couple types of v8's as well as the suburban. so as i said before just make sure you transfer the engine with the computer and you should be alright.
