Find a stock L92 camshaft. The stock 2007 6.2L L92 engine in my Denali makes gobbs of power. L92 built after April 1, 2006 didn't have AFM and does have VVT.
If you need a VIN# I'll give you mine.
Or call Summit Racing and see what they have.
L92 info here:

Did you keep everything pretty much stock or did you update lifters and springs as well
Found the cam its Pricey as much as the Cam Motions but its available immediately which is something I want since this is my daily and my beater currently is trying to Carbon Monoxide poison me as I drive

Ok so as I was looking at other posts i saw many people pointing at these cams and when I was looking at the specs there has to be a typo right? can a cam have a 350+ duration. I feel not even stage 3 cams have that!!! so the picture I shared the one on the right is for the l92 engine and the one one the left is for the L9H.
The website on all cylinders they are identical specs, the only difference is price so cheaper one here I come!!! lol

Camshaft part # for the L9H is 12623065, not 12711967 (left side picture).

Thank you all for your help.
I went with the L9H cam to save a few bucks and buy some other goodies to make this engine better and a future candidate to cam up and drop in in a resto-mod if the truck ever takes a dump.
I bought most of the goods on rock auto and Michigan Motorsports and I even splurged a little on needless, but because I can be so extra sometimes, extras like a stud kit the new LS6 Valve springs and the hollow stem valves. Now my wife can drag race the neighbors black escalade on her way to drop off the kids in school.
Ill keep you posted on this second adventure or rebuilding this engine.
Then I will swap my tahoe's rear end on this bad boy and swap the 4wd internals on the Denali's AWD bad boy to make her go go go. My 2002 turd has 3.73 gears, id bet this six speed would fly with that, the heck with the MPG!!!

Hello my fellow contributors on this DOD journey, so the Engine is out and dissembled. one of the AFM Lifters has a shiny spot on the inner corner (I'll show pictures later) the cam is not chewed up at all (I was expecting some carnage but it has some uneven wear patterns kind of odd. My camshaft Bearings are a bit discolored, I showed pics to my cousin (works for Toyota) and he says his recommendation is changing out the cam bearings, I was hoping not to touch the bottom end but I guess I have no choice so this DOD is sending me down a rabbit whole to taking every bolt right out.
Will the main caps be reusable if not damaged or is it better to just get all new bearings since everything will have to come off?
I will post pics shortly
Lordy Lord!!!

Is that a rebuilt engine? Factory cam bearings would show copper in the worn area. That cam bearing is in great shape if it's original.
