I'm researching for a used none DOD/AFM LS2 engine to swape into a 07 Trailblazer.

mine current engine 5.3 HL6 has the DOD (displacement on demand) AFM (active fuel management) w/ collapsed lifter #1 that I'm wanting to delete or better upgrade to LS2 power.

I have been told that some GTOs did come w/ AFM/DOD how can I verify this?

any tips is appreciated

No 05/06 gto had afm or vvt. 04 is a gen3 block so won't swap in directly
