We did this to a 07 caddy ext..
we swapped the front cover for a LS2 one (cam gear too) and bypassed the vvt solenoid, no pcm problems what so ever..
the truck now runs 12.74 @ 7600DA ... 6600lbs!!!!!!!!!!!!

we really did not look at it that well, we were rushing to finish the truck but we think is oil related too because the "driver" of the cam had some holes in it and a "pushable" pin.
let me see if i can find it at the shop today and i will take some pics of it

don't waste your time with mast. they only sell the whole deal with an engine. they wont sell just a vvt cam.
see nycblazers post for links to your parts list.
I'd change all of the lifters and lifter retainers to the lighter ls2/ls7 style instead of the vvt ones.

The truck is beyond stock just to say something LOL...
really moving a 6600lbs truck at 7600 DA required:
orange block / heads / cam
procharger
th400 (6 speed tranny did not lasted 2 full runs
)
yank is making us a custom converter, hope for the best
the truck runs this times with a HUUUGE audio system and 24" rims, really impressive to look.. we still have to run it with small shot too
couple of electronic stupid **** from GM that we had to take care of with the "mexican" way but so far so good...
im uploading the pics of the vvt system right now...

too big. wasted power. an ls6 or ls2 pump is more than adequate. also no chance of sucking the smaller pan dry. with the smaller pan and no vvt its overkill.

the only change in the cam is the driver itself, its a 1 bolt cam.
basically the driver bolts into the cam, centering and attaching the cam gear at the same time...

I dug up the Gmhightech issue that announced the LS3 and there is a pic of the cam there as well. The article doesn't go into great detail about the L92 its mostly LS3 related but it does show a couple of pics. Only thing i noticed that appears different to me is the second cam bearing race has a groove in it and a hole/s? I've never seen an LS2 cam so I dont know if they have this also. Nov 2007 issue.

would this kit work
2007 LSX Cam Install Kit
This kit allows for a proper installation of an aftermarket cam on a 2007 or newer Trailblazer SS or Corvette. These vehicles have a newer cam design to go along with the variable valve timing available on some of the other GenIV motors. Simply using an older LS2 cam sprocket will not be good enough because of the differences between the ECM’s.
