And measured with the vehicle running in Park or Neutral so there is fluid being circulated. You would be amazed at how high the fluid was in my tranny once I figured out what I was looking for... 3-4 inches

So now you all have me reconsidering on the 3.73 gears. I had just made a final decision with Doug on the phone today, and then I come on here and read this stuff!
You're making it pretty damn hard for me to make up my mind. Honestly there has been nothing wrong with the 3.73 ratio in daily driving, aside from the 17-18mpg around town and 25mpg on the interstate. I enjoy the quick acceleration, and it gives me opportunity to swap in a really big cam that makes peak power up higher.
However, I can totally understand the argument for 3.33/3.43s. They are a better "middle-of-the-road" ratio and would suit my current setup beautifully, especially on street tires (not enough grip with the 3.73 ratio). I'll think about it more and give Doug a call tomorrow.
It seems as though the popular opinion is to go with the 3.33/3.43 setup. Any other opinions and/or reasons for choosing a particular ratio?
