I have a 2006 CRew cab half ton with the 5.3. I am wanting to install a 2002+ ls6 cam in it and replace the springs with the comp cam 918's. curious if anyone has done this or ever seen the dyno #'s of this. I was told it would add up to 40+ rwhp.??? Not sure if i believe it or not, so thats why i am asking you guys. thanks for any help. casey

here the specs from my stock cam to the 2002+ ls6:

I posted a few links here regarding the LS6 cam. Scroll down and check them out:

Any reason why you don't want to go with a slightly bigger/different cam?

I have the same truck and am looking for good reliable mods to do to mine also. I am in the process of searching the forums, but would like to know what results others have gotten from their 5.3's. What rear end do you have in your truck?

look into an 01 z06 cam. it will better suit your needs.
