AFM or not?

I have a 2007 silverado classic with 5.3. Engine vin code is Z. I am trying to determine if the truck has active fuel management or not. Thanks for any replays.

I didn't notice it said classic. So I'm guess you have the slanted headlights like 03-06. They didn't start doin the AFM till 07 with the newer body style trucks. You shouldn't have it if you're in a 07 classic
