Beware of those cam specs for the LY6 PN# 12629698. I have that camshaft number listed as for the L76 which also uses the 12625438 which are AFM cams.
When I get around to tearing into my LC9, I'm strongly leaning towards the LY6/L96 12625440 which is 196 208 .467.479 116. That's as close as I could find after months of searching.
That being said, GMPP, BTR, Comp Cams, Cam Motion and Vinci all sell very mild, low lift cams for our motor but nearly all are Gen III style. All are between 203 In - 216 EX duration, none over .530 lift and 113-117 LSA.
The LM7 is definitely not equal!
The 12561721 in the LQ4 and LQ9 would be an equivalent Gen III camshaft.

Yeah if you keep the vvt the L96 will work... It's not ideal but it's so puny it won't really matter and it's not really any different than the LQ4 cam beyond the vvt aspect. Finally finding it's specs I really should put a cam in my 17 HD lol.

For the engine type (L96, LY6, etc) then I go here https://www.gmpartsdirect.co/
and input that same vin # to look up cam part # and that is what I’m coming up with. Great input thanks.
The L92 specs came from Crower Tech Support. Im waiting for a response for the LY6/L96 cam specs.

I like the idea of VVT and it is certainly more reliable than AFM. I've disabled AFM and next year or so will remove it physically from the LC9. My LC9 does not have VVT, it's a 2009.

I’m searching Auto Trader for vin numbers for 2007-2010 Sierra 2500 trucks then I go here https://service.gm.com/dealerworld/vincards/

But the 2007-2009 Silverado 2500/Sierra 2500 LY6 Gas and 2011-2015 Silverado 2500/Sierra 2500 L96 Flex Fuel motors are using cam p/n 12626660...
The LY6 and L96 where both produced in 2010. Not sure what determined which got what? Probably just a transition year.
None the less I'm not sure what the difference is between the two cams but I'm sure it's minor and both cams should work. The 12626660 cam is about $40 cheaper!
