yeah, one of the guys i hung out with as a kid had a 72 SS chevelle with a 396 and 4.56s and they are a blast but would get to be a bit much.. my last challenger had 3.91s and by the time i got rid of it i hated that gear.. i think i can fit 29 (MAYBE) a 30" tire which would help bring that down a little.. i'm just being lazy and not wanting to change the gears out..
