Sorry for the thread steal but thanks for all the suggestions...now as far as keeping VVT, is there an advantage on the torque curves? i dont wanna loose any low end torque and have to wind this up all the time to get any power...this is a heavy truck so the low end is what i love about it so far...

From what i gather right now, and looking at some ETs between few similar cars, is that blower makes amazing low end torque for what it is with the stock motor...
A similar denali like mine pulled about 13.5 in the ET at about 100 something.
A same truck, with just a few bolt ons ran a 14.5 at very slightly lower ET at about 100 something...seems like the low end gets it out the whole, but runs out of steam up top...not sure what cam will help with what, but i dont want to suffer the low end torque and weather that will be sacrificed at all with the addition of the LS9 cam without VVT, even though people seem to love the LS9 cams like stated on this thread...

So after doing little research with my friend, i decided that i might take the budget way to swap the LS9 Cam into my L92 maggie setup...

After some PN searches, i also came up with these spring part numbers:

L92 springs : 12589774
LSA springs : 12589774
LS2/LS3/LS9 springs : 12625033
LS7 springs : 12621428

With that in mind, im assuming the stock L92 springs are the same as the supercharged CTS V, which im guessing no spring swap is needed?

Ill have to get the PNs for the above parts so i can order the parts if anyone has them handy...

Sorry to resurrect this thread, but I'm very new to LS engines. I have my 6.2L L92 torn down to freshen up while I repair a bad lifter and cam. I'm considering to upgrade the cam to the LS3. I understand that I would have to delete the VVT, but nobody talks about getting the engine computer tuned after a cam install.

Would I need to get my engine's computer tuned after swapping to the LS3 cam?

If you go away from VVT, you will need to reflash as all those VVT values in your tune need to be updated for the non VVT cam / new timing
