I just purchased a new LY6 to put in my 2004 avalanche that currently has a 5.3. What will I need to do to make evrything function correctly. I want to source all my parts in advance.

Crate engine for sale 6.0
I have an 6.0 engine fresh in the crate ready to go for $3500 OBO
It’s an LY6 with the L92 heads it also has the large Throttle Body I think it is the 102mm but I will need to put calipers on it to be sure. Its definitely larger than the one on my 5.3
O miles ready to go
