Do they even make these gears?
The reason people recommend 3.73's as the highest as that is really the most gear you need with these cars, and arguably, you don't even need that much gear. Since you already have 3.23's, without a doubt nearly 100% of everybody will recommend a stall converter if it is outright drag racing speed you are looking for.
Gear swaps make the most sense to casual guys who have 2.73's and are looking to wake the car up. 3.23's are a good working gear already so the money is better put elsewhere.
You can easily become traction limited with even 2.73's and a stall converter.
anyone else?
