The Atlas is Pushrod. I think because of a need for GM to get away from the architecture... they have gone completely towards OHC designs outside of V8s... where they are still class-leading.
Having essentially one engine base (the HF) is both logical and cost efficient. They seemed to have adopted this strategy across the board. The V8s are LSs, the 4 Cyl are Ecotecs, the V6s are HFs
