First, let me say I have read the sticky 3 times, thouroughly.
Currently I am running 2.73 gears in my stock 68 GTO/400, with a 4 speed transmission. I am scheduled to get these gears swapped out in three weeks. I have already bought 3.73s, but after reading the sticky on Gear Ratios, I want to be able to drive it both on the highway and have some power in town, so I am changing directions and really think I want 3.23s or 3.55s. The problem with my current gears is that I own a muscle car and it will not smoke the ONE tire. (I have bought an EATON posi 3 series carrier to go with my new gears.)
My goal is not for the car to smoke both tires forever, but I would like for it to chirp them a little bit, and then set you back in your seat. (That is what a muscle car is right?) This car will not be raced, but it feels like a dog right now with these gears and I don't like it. If you have experience with these gears, and have an idea what effect they would have on this car, please help!
