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.

I made a quick Excel spreadsheet using a stock LT1 dyno I found online and the different gearing options. I left the rear axle ratio constant at 3.42 even though they don't come that way stock. Each tab represents a different gearbox.

Ideally, the shift point is where the horsepower curve in one gear intersects the other. Unfortunately, this never happens on the LT1 no matter which gearbox is run, as far as I can tell. The engine needs more RPM.

Spreadsheet - right click, save as please

My current car for comparison - right click, save as again please Obviously, I have not formatted the X axis the same as the LT1 version, but you get the idea hopefully.

Let me know if I screwed this up.
