I am considering the purchase of a dedicated event car to take to HPDEs, Time Trials and Hillclimbs. I will most likely contest a Street Prepared class during the timed events, but have not made a final decision. The value represented by the 4th Gen F-body is attractive. I have yet to uncover a single source buyer's that details perfomance affecting year-over-year changes and options. Is there such a thing? Any links or attempts at putting together a brief one here would be appreciated.

So perhaps then the purchase of a 93 would be a better idea? Seems like the 3.42:1 rear is a common fitment for many years of V8 F-body and I imagine it would not be hard to source one.

It won't be hard at all to find a 3.42 rear end as all of the 6 speed cars (except the 93's) came with them. Plus drag racers frequently sell them for next to nothing when they upgrade to a 12bolt or a 9". I bought mine complete (but without brakes) for $200 a few years back.

As far as the different 93 transmission's go the one you want is the M29 (should be listed on the options label in the glovebox). All M29 cars also came with 3.23 gears which are option code GU5 (also listed on the options label). Luckily 99% of the 93's out there have this transmission.

The alternate 93 tranny is the M28 which came with a 2.73 rear end. From what I understand these are very, very rare. I remember seeing the production numbers at one point and fewer than 100 cars were made like this.

Does the 93 gearing make much of a difference? I'm not sure, it does make 5th gear more usable but thats not an issue for autocrossing. JeffM who has a 94 Trans Am w/3.42's has driven my car and I don't think he noticed the difference.
