Are you sure it's not on the other side? :O
IIRC cam phasing mechanism is significantly wider than the cams themselves, that would explain it, assuming it's not missing from the other side.
EDIT: upon further examination of Kostamojen's pics, nope that has to be the cam phasing mechanism, it's there on the other side...dunno what I'm seeing that you're not.

Oh and Dimman, I don't think specific torque is that reliable of an indicator of how efficient an engine is. Remember for a given displacement, the engine doesn't necessarily pull in that full volume's worth of air. Ferrari with its ridiculously high specific torque is in part because they have the money to ensure that the engines have lower losses in some respects, but the cams are designed to pull in as much air as possible, and this directly reduces efficiency. In addition, at part load, it causes more pumping loss. When manufacturers making normal cars that average people use, they can't have continuous cam profiles, and they need to think about things like fuel efficiency, so even at peak torque they aren't quite as good.
