Thanks for the help! My only concern is that I only have 1 exhaust pipe. What do I need to buy to make it work? Or does my engine look like that too, and there is a part that merges them into one? Sorry my wording is pretty bad.

It'll work just fine. Your engine has 2 as well. Should just be a direct swap. Take yours out, put this one in, have your PCM tuned for it, and you should be good to go.

Also just to throw this out there, you could also do a 5.3 swap, which won't get you much more HP than your current 4.8, but they're also a LOT cheaper (i've found 10 for 450 dollars at my local salvage yard). You could spend the extra coin you save on some on the motor to get the extra power your searching for.

So if I were to get an LQ9, do I have to find one for an automatic one. (being my truck is automatic) Because Looking on ebay, there is one with 64K miles for $2600. (I don't know what a good price is, or if that is considered low miles). But it doesn't say if it is auto or manual... Do I use my own transmission, or can I tell by the pictures? Thanks.
6.0 LITER VORTEC ENGINE MOTOR CADILLAC ESCALADE LQ9 64K DROP OUT | eBay
If you look at the pictures of it, does it look good? Or does it look trashed? I don't know much about this kind of stuff. aha. Is that a decent price? Thanks again.
And I just noticed that the LQ9 has two exhaust pipes... My truck has 1. What do I do about that?

Did the Cadillac LQ9's have a Vortec Max engine cover? I thought they only had the Cadillac crest logo.
Anyway the price is probably decent assuming the 6 month warranty actually means something if there's a problem. You're buying extra stuff you don't need (pedal assembly, PCM, harness, etc) but you might be able to sell some it to recoup some of your cost. The LQ9 was only available with the auto to my knowledge so it will bolt right up to your transmission. You will notice a decent gain in performance between the two engines.

The Vortec max red lettering cover was 06-07
In 03-05 it was Vortec 6000 in silver
The LQ9 was only available with the 4L65E option RPO code was M32
The 4L65e is the same basic 4L60E transmission but had a few minor upgrades internally like 5 pinion planetaries to help with the higher output.
Speaking from experience there is quite a difference in going from an LM7 5.3 to the LQ9. Even the LQ4 has a much stronger feeling in stock form.
Your only going to be able to max a 5.3 out around 380RWHP with out going forced induction. The 6.0 will probably get closer to the 440 RWHP range.
In my opinion the money your going to spend on a 5.3L with bolt ons you would be better off spending up front on going with a 6.0L. At least you will notice a significant gain right away. Then you can save up again and start building from there if you have a quest for more power.
If you have a real small budget then the 5.3L cost around the same as the 4.8 and I would definitely put a 5.3L in over the 4.8 any day of the week.

BTW you can get a complete LQ4 for $1000-$1500 and save a few bucks vs. getting the LQ9.
The only reason the LQ9 has a higher HP rating is because of the compression and tuneing for the higher ocatne.
You could get an LQ4 for now and later install 243 heads and achieve basically the same thing.

my 4.8 in my ecsb 4x4 with 3.73 gears likes to downshift going up hills on the highway, i am on a tight budget so thinking of getting a 5.3 for it, does the 5.3 have enough more power than the 4.8 that it wont have to downshift on every hill?
