Does Ly6 Have Dod?

Mines a 08 ly6. Just vvt they didnt come with DOD. Should be able to just swap the cam, sprocket and timing chain to a non vvt one. Lifters are normal style so no need to change those.

Does LY6 have AFM?

The LY6 engine came in Chevy and GMC 2500HD series trucks, vans, and full-size SUVs from 2007-10. It's the next best thing to an LSX block when it comes to adding boost or nitrous. The rugged iron block 6.0L came with VVT, but without AFM, which saves you the cost of an AFM delete kit.

Is the LY6 a good engine?

After installation of the LQ9 cam, the LY6 6.0L proved to be a decent performer, producing peak numbers of 443 hp and 467 lb-ft of torque. Torque production exceeded 450 lb-ft for a 1,000-rpm spread. For guys looking to upgrade their iron horse 6.0L truck engine to LS3 status, the gains were pretty impressive.
