with the larger rear gears you shift through the gears so quick just driving around with the light wt. cobra and all the power. i don't have that much engine but do have a 3.73 in one and a 3.55 in the other, wouldn't go larger then 3.73 and could use a 3.55 or thereabouts real easy all day long. with a 3.73 or 3.55 you can accelerate in 2nd and skip shift to 4th pretty easy for street driving fyi.
