my wife drives a 2004 tahoe with a 4.8l, i would like to swap this with the 5.3l, my question is this. is it a straight swap or are there problems that need to be addressed, any info would be great.
i'm new to this forum, if this info is already on here how do i access it.

 

Should swap easy, but you need the computer for the 5.3, and maybe the harness for it to.

 

Welcome to the forum. Good luck w/ your swap.

 

unless your getting the engine free it might be 100 million times easier to sell it, and buy one with the 5.3 in it...
