FWIW my 07 6.0 2500 sub has VVT....presented a few problems when we first tuned it for the blower, since the shop is 95% vettes, and well vettes don't have it.

yup stock internals.
We had problems with tuning it with the blower because we didn't realize there was a whole other page of tables associated with the VVT stuff (and also a new version of EFI live at the same time to complicate things further) once the guys figured out that VVT table things fell right into place, but before that they had so much timing out of the truck and it was still pinging with the boost backed off, 93, octane booster, you name it...but the VVT stuff was entirely on its own and independant of the normal tables...
(what i was told I don't touch laptops and software ever since wiping out a motor 5 years ago trying to learn DFI)

Ok so I just want to clarify here. 08 5.3's and 6.0's for a cam swap all you need is the LS7 sprocket? Not the 6.0 needs the sprocket and the 5.3 doesn't or vice versa?
