It means you have the optional performance gear ratio of 3.23:1, rather than the base ratio of 2.73:1. This was only an option on auto trans cars, all the 6-speeds received 3.42 gears with no other ratio being optional.
PS. This option also means your car came with the aluminum driveshaft stock (2.73 cars still came with a steel shaft).

Yeah, but not by much, maybe a tenth or two; that's about it. Reason being, the 4L60E has a very aggressive internal 1st gear ratio (3.06:1) so launch is usually stronger than most street tires can handle anyway, thus traction becomes more of a limiting factor than gear ratio at launch (that, and the fact that LS1s make great torque even at low rpms, so they get moving pretty good even with a rather mild gear). Now if you put two otherwise equal cars on competition tires that would deliver 100% traction for either gear, you'd see a bigger difference in performance between the two ratios.
Of course, launch isn't the only thing that gears effect. As mentioned above, the smaller (numerically) your gears, the more rpm drop you'll see at WOT upshifts. So there's a slight performance reduction in that respect as well.

No I meant as far as identical options.... Was just trying to say that if you took one car with a 2.73 gear and made a run down the 1/4... then changed the gears to 3.23 and nothing else... it would do a faster pass.
OP asked if the $350 option was a waste, im just trying to say that it is not a complete waste.
