U can use any of the LQ4 or LQ9 engines. Good luck finding a LQ9. Any year is ok i prefer 02 up. As far as the swap itself. U can use your intake and injectors. They are the same as on a LQ4. The LQ9 intake has 26 lbs. injectors. The tune u got in your 4.8 wil run the 6.0. It will set a O2 code in the winter saying its too lean. For peak performane u want it tuned right. The swap is simple plug and play.

Like said, but I would go with a 05 up, 05+ have the ls2 internals in the lq4-9 which are beefier the the pre 05's. You can use everything off your 4.8, besided your pcm, you will need that retuned. i would also look into a trans an rear shortly after the swap. It is a straight swap, everything plugs in..

The LQ9 had the beefy internals since 2002.

I have a 2002 LQ9. I used everything off the old 2000 4.8L, all accessories, wiring, and intake. I'm don't think the LQ9 has 26lb injectors, I think they also use the 24.7's.

so the lq4 i could use a long block and the lq9 i would need the injectors

Yes the 9 did and not the 4, but in 05 they all received the LS2 internals.

you need an engine. everything else will swap. it will crank and run but will be lean at wot. get a tune and then it will be fine.

I'm almost positive the LQ9 and every other truck v8 uses the same injectors. I do think it's odd though that an LS1 has 28lb injectors whereas a 6.0 only has 24.7lb'ers.

I spent a lot of time looking for an LQ9, mainly because I knew it had beefier rods and higher compression. Also, I really wanted an 05+ LQ4 (that also had the beefier internals) but they were just out of my price range. An 05+ LQ9 was way out of my pricerange. So I settled for the 02. Let's just say it turned out just fine. My rear tires hate me

Same injectors, if you plan to add a cam, boltons and whatever you will need bigger injectors and a set of 8.1's or the marine 8.1's injectors. If you ever plan on going FI I would go with a lq4 since it has lower comp, will be a lil more boost friendly. Either way if you get a pre 05 or whatever, they will take what ever you can put at them for the most part. You can find a 05 up for 1200 or less if you look. I picked mine up for 1200 shipped to me with 11k on it..
