I have 3.73's in my 92. 2k rpm in 3rd, 35mph. 2k in 4th, 50mph. 2k in 5th, 70mph. 2.5k in 5th, 90mph. As for the MPG, dont know how much worse it'll get cause i had mine done after a lot of other mods and i get 8mpg. but if its your daiy driver i suggest 3.73. if possible get a POS for a daily and get 4.10's

finally getting 5 lug conversion done next week, had to sand blast the kit MPS Salvage sent me and rust proof it, but anyways, putting bullit wheels on it, 9" at back with 255/40/17 tires...also puting in 373 gears, I keep hearing about tire size, I'm guessing more grip and faster take off, dunno kinda new to this area of mods

i have a five lug on my fox with 9inchers there pretty solid..and i have a 373 in it too so its pretty nice, i went from stock gear (273) to 373 its a big jump but its fun. my car is basically stock a few bolt ons but it works good and gas milege isnt to hurt by it so have fun
4.10s behind a C4 in my 94. I had a 3.73 installed before. There is a BIG difference in gas mileage. It is def worth your money if you are wanting a quick upgrade. If you have a stick I say drop a 3.73. If you had 4.10s behind a stick you'll need the right kind of tires to get ANY acceleration lol.
Go with the 3.73's for sure, 3.55's are good for a woman driver than wants more out of the car, but still wants good mileage and not alot of noise. I had 4.10's in one car, they are too much for a true daily driver.................unless its a AOD car.
