another 2.73 gear change thread What should i go with? my car is pretty much stock accept for very minor boltons, a stall may be in the near future, and i'd like a gear that i could benefit from, but would also be good as a daily driver. I do mostly city driving but that may change within the next year, so i can't afford to rev extremely high on the highway.
I'd like to know you guys' mileages, times and what's best for the SOTP factor.
Thanks!

my 273 - 373 swap got me 1 mph and .2 et in the 1/4. mileage should be up in town (driving like grandma) and down on the highway. my 273s got 32 mpg on the highway, i know there's no way that my 373s would even be close.

Going from a 2.73 to a 3.42 dropped my top MPH from 162 to about 135 though.

I would say a nice torque converter and stay with 2.73's or 3.23's
With a ~3500 stall my 1/4 mile improved none going from the 2.73's to the 3.73's, but maybe my torque converter just liked the 2.73 gears.

3.42 would be a good gear if you think you'll be on the highway a fair amount. Going to 3.73s will be having your OD go out on you now.
Better to do the stall first and then see if you need gears.

Right now if OD didn't work he would use 3rd gear, giving him a drive ratio of 2.73 (1.0 x 2.73). Thus if you have 2.73s you can drive on the highway in 3rd and see if you really like turning that level of rpm. It's fine for short drives in the city, but I find it a bit high for long drives.
