K, dont think its daily driven as it is

If your serious about this one, 4.10's on an automatic is insane, unless its a v6, or your switching to the T5 like uve said in another thread which IMO is pretty dumb. In an automatic, on a highway your gonna be doing 70 at @4100 RPMS ... You'll basically have no top end... Highest I'd go is 3.73s which is what I have in my car now... and maybe for your car, a 10 bolt might hold up pretty well... you might wanna have some baseline HP/TQ #'s before you choose the appropriate TC.
