waiting for a reply on if the motor will come with the wire harness... seems that most of the 6.0l come outta Escalade's.
escalades & SSS had the LQ9 (the higher-output version). that one's typically the more desirable one. the LQ4 came in everything else

the lq9 has something like 10:1 compression and the lq4 has 9.41:1 thats what i found earlier and a diff hp rating thats about the only diff rite?
i know the LQ9 has flat-top pistons resulting in the higher comp ratio, but i can't remember off-hand what all else, if anything, is different.
just don't get a 99-2000 6.0
they had iron heads & need a crank spacer to fit - i can't remember why all else they're the unwanted red-headed step kids, but everybody says to get at least an 01

Is anyone actually serious in doing this? I am very interested in how easily this could possibly be done. Externally, how simular is the 8.1 blocks to the LS style? (engine mounts, exhaust matching up, etc)

there's a thread on FSC where a guy did a writeup of his 8.1 swap into an 04 RCSB with the 5 speed
