Default Ls3 dod?

Hey guys just picked up an ls3 top end from a C6 grand sport that had the engine replaced by a Chevy dealer. Car was a6 but I noticed it had the DoD passages under the valley cover. Pretty sure C6s didn’t come with afm or DoD. Interesting find-heads were 821s and def an ls3 Intake.

The LS3 block has the same oil passages for the DOD LOMA as the L99 blocks. If I’m not mistaken, the block is the same for both. You are right that C6/LS3 didn’t have DOD/AFM or VVT.

No AFM or DOD on a LS3 engine

Yes. It’s the same block for the LS3, L99, L92 6.2 liter motors. You can use or disable DOD/AFM and or VVT on that block, by using the requisite parts.
The LS3 (C6/ manual trans 5th Gen Camaro) came without either DOD/AFM or VVT, the L92 (Denali truck/Escalade) came with only VVT, and the L99 (5th Gen Camaro w/ auto) came with both DOD/AFM and VVT.
