So I have a 03 yukon denali with the 6.0. I was given a 05 chevy tahoe 5.3. I was wondering if I can swap the 5.3 and engine harness into the denali? I'm wanting to build the 6.0 for my f body. But wasn't sure if everything would swap over with no issues. Any input would thanks.

They're both Gen III truck engines. Should be plug and play....

Kinda what I thought. Just didn't know since the 5.3 is a L59 with the afm. If that would change anything

The L59, being a Gen III, does NOT have AFM/DOD. If your engine has that, it is Gen IV and is not an L59.
The L59 is basically the Flex-Fuel version of the LM7.
