More LS9 Intrigue

Over at Corvette Road, they've got a CAD drawing of what may or may not be the LS9. Looks weird to us. And why a CAD drawing with the engine covers on. From the width of the thing, it could be DOHC, as rumored last week. Something seems kinda fishy about this to us, but we can't quite put our finger on it. Go check it out, come back and weigh in.
