Engine swap to 6.0 question...

I have a 2003 Chevy Tahoe Z71 4x4 with the stock 5.3L
What would I need to do to put a 6.0L into?
I already have the Diablo tuner I use on it, but I feel I just need a bit more power.
Its not that its bad or horrible. I am just thinking a 6.0 has more torque and would not need to downshift so much when pulling hills or when I have 3500# trailer behind it.

Am I crazy for thinking this will improve my power needs or ???
Is it simply changing out the long-block or is there more to it?

I will then use the 5.3L out of my Tahoe in my 1968 Chevy Shortbox project

Thanks for your input...
