I know that pretty much any mod from the 4.8 will fit the 5.3 wil fit the 6.0 and all combonations, but what are the different internal components that stop a person with a 4.8 from just boring and stroking (whatever is neccessary) to obtain the 5.3 or 6.0.

My question sparks from seeing plenty of people swapping out the 4.8/5.3 to the 6.0 and I figured if a simple rebuild with bore and stroke were possible somebody would already be doing it.

If this question has already been answered I'm sorry, I searched but couldn't really find anything.
