I have had 2.73's 4.10's and the current 3.42's.

By far the most enjoyable to race and drive is 3.42's with the pt4000. I would, depending on how much you dig and the power you make, Highly reccomend the combination.

With 3.42's Traction is much easier in first and the car with tall gears and an efficent converter makes for a SICK pull on the top end. Also I like how the rpm's look for the typical "rolls" that occur.

This combo will also allow to comfortable cruise at any sane speed. I knocked down about 22 mpg on the highway doing 70+ with a tune that is still being leaned out. Will easily be doing 25 mpg, probably higher if I wanted to really baby it and do 60.

my converter is gonna be about 3k-3600 due to when i run n20, its gonna flash a lot higher than with n/a. N/A i am making about 500tq and with the spray its 830ish. I think ill try out the 4.10's since i have a 9" and the gear changes are easy.

Since it's a 9" try a set of 3.90's I think they would be the best of both worlds. It depends on what trans and tires you are going with. We are running 26" tires MT drag radials and ET streets. Looking at going with a 28" true drag slick.
