If I were you. I would go with what you wanted and don't let gas mileage be your deciding factor. The difference between 3.73's and 3.90's in gas mileage is VERY slim. Its not worth getting a gear ratio that you arent completely satisified with.

split the difference and go with the 3.90's. That' what i have anyway.

Thats what I did also, ended up going with 3.90's. If I were to do it over again I would go 4.10's + without a doubt.

3:73 sounds right for me.

3:90s arent that cheap anyways, just do 373's thats what im going to do..... everyone you talk to that has 355's say they wish 373, some with 373 say 410's, some with 410's say 373's i say just do 373

honestly if you're going to build serious power low gears are bad

i went with 3:55 but they were also free. if i had to buy them then probably 3:73's.
