Which 6.0 should i buy?

99-02 is DBC which will be compatible with your current setup.

03-0x will DBW which you will have to purchase the Tac module and pedal for DBW

05-0x you would have to make provisions for Efans since those motors will not have a mechanical fan

If it was me, I would reuse my old harness and throtle body (if going with 03 and newer) and it will be easy as cake

So you think going with an 03-04 lq4 is the way to go? its not a daily driver so i will be putting a healthy cam, LT's, etc in. I just dont want to get a motor that has is going to be a pain versus a year newer that will almost drop rite in. Thanks

With your harness, throttle body and computer it will be a direct replacement.

i have a 99 ecsb that had a 4.3 now have a 04 lq9 (excalade) dbc since you have a 4.8 dbc youre good to go, not much more needed except for a tune... all your accessaries will bolt up. even intake.

Well I guess i'm on the hunt for a 03-04 lq4 or lq9 then. Of course the three 6.0 engines that are local are 01-02. I can get one for $700, is it worth the hassle or do i wait it out for a 03-04. Thanks guys I really appreciate the help!
