I pretty much agree with what's been posted. I think high 13s for the 3.6 and bottom to low-13s for the 6.2. Sticky tires should put it pretty close to high-12s I think. I keep thinking about the weight of the car in general and can't help to be a little concerned, but an LS2 GTO would run low-13s with a good driver, and I'm sure an LS3 Camaro would be at least very close to that. I keep reflecting on an SRT-spec' LX-car and think that it should at least be on par with those, so I think we should be looking pretty good, regardless.
