L8T 6.6L Capabilities

[C/K Man]

This article talks about the L8T block.  Appears that it is quite some hunk of iron, stronger than the iron 6.0L block.  Seems like overkill even in an HD pickup,  I suspect the L8T was designed for heavier commercial vehicles:

So it's capable of higher power and rpm ratings than the 6.2 and they left room for more bore with thicker cylinder walls. Maybe they wanted to leave their options open in case the hybrid market hits some speed bumps.
