I'm sure someone else that knows better will chime in, but I THINK it is a drop in job and just your ECU will need reprogrammed. The 6.0 has great power, you will most likely love it. I'm not knocking the 5.3, but my current Denali has way more power than 02 Tahoe with the 5.3.

all swaps over, will run with stock 5.3 computer, but to optimize, have it tuned to the 6.0 parameters.

But will the stock transmission handle the power difference from the 5.3 to 6.0?

The interwebz would be an ideal place to start :shrug:
