Canuck: my wife has a 496 powered Sub as her daily driver...thing pulls like a mule & will FLY! She absolutely loves the thing...can't get her out of it for another rig (unless it's my truck!), 'cause I've been trying for a couple years. Also, it actually gets better fuel mileage than my 496 2500HD...both have 3.73s, but I'm guessing her 4L85E trans is more efficient than my Allison and her Sub is a bit more aerodynamic...if we can ever get to good road, she can knock down mid-teens...
