4.8 swap?

[william42]

I have a 2004 tahoe with the 4.8L. can someone help me with what all has to be done to swap in a 6.0? what year model motor would i need to look for and will it bolt right in?
are the wiring harnesses the same and do i use all of the 6.0 intake and injectors and things or do i use the 4.8 stuff? any other info would be greatly appreciated? also can i just have the pcm flashed or would i need a new one and what would i look for?

once again thanks for the help,
will

No it's impossible. It'll be easier to just sell it and find something with a 6.0.

thanks

what year model 6.0 do i need to look for and do i have to use my intake, fuel rails, and injectors off of my 4.8 or do i use the 6.0 stuff? and will all of my front accesories work on the 6.0? which flexplate do i need to use to bolt the 6.0 to my tranny? whatabout the tb which one do i use?
i know someone can answer these for me?

I'm not sure why he is being a dick Any year will work. All the accesories will work. The differences will be whether the tb is drive by wire or cable, and whether the 6.0 you get has return style or returnless style fuel rails. And you'll need a 6.0 flex plate.

So if those things are different just take your intake, rails, and tb off the 4.8, get new intake gaskets and put it on the 6.0.

He's not being a dick, this question is just asked and answered every day.
And no, every year won't work. The long shaft 99-00 LQ4 won't work with a 4L60e.
OP, all you need is a 01-06 longblock. All your accessories and intake, injectors, TB etc. will fit. PCM is the same, just get a tune.
Seriously though, hit up the search button and most if not all of your questions will be answered.

That's all that needed to be said. First impressions last a lifetime. BTW thank you for correcting me for the 99-00. I did not know that.
