Seriously, you will be able to rip the tires on demand with that 4.10. You could probably scratch 3rd.
I define "useless" as not having time to look at the street to see if you're inbetween the lines while you have it floored. You just have to keep your eyes on the tach.
Try the 4.10 for a while, what the hell. It's easy to swap out.
