They probably want an air of sophistication by using a dohc engine. Too bad, they could have used an LS small block and had the same or more power for less money, weight, and similar or better mpg to boot. Oh well I guess.

blown northstar FTW! lol! Sweet ride! don't know why they didn't just use an LS2 or something. but that 4.4 SC DOCH V8 must go. and its a sweet looking ride! C6 chasis?
