I saw your post on Corral. Almost a hundred people have viewed it and no real proof. I'm interested in this as well.

 

I can't help you out with your application, but the difference I found between the 2 gears is quite noticable on my friends 89's. the car with the 4:10's just seems to have more pull throughout all the gears, but at the same time it seems like alot of people are forgetting that your rim and tire size also affect the gears. You cannot really compare a car identicle to yours with 4:10's if he is running 15 inch drag lites and your running lets say 17 inch cobra r's.

 

also with the 4.10's it seems like your more into the power range (although I cant really say because I only driven a 373 gear car once up and down a street)

with the 4.10's every time you shift you get thrown into the seat, I think with 373's the RPM's would drop too much to get that.

 

This has turned out to be an excellent question! I am also waiting for the person that can post the required time slips that will "prove" what everyone "thinks". Looks like it may not happen

 

I've never seen actual results just people say that it feels better. that means dick all at the track

 

ok 87-98 t-5 tranny, 99-01 1/2 t-45 tranny 01 1/2 to 04 3650 all completely differnt gears which will effect you rear gear ratio.

I have had every gear from 2:73's all the way up to 4:10's exclude 3:90's.

for a n/a fox 4:10's no brainer here.
nos car or supercharged 3:73's and extend the rev limiter a little.

same as above for the t-45

Now the 3650 that i have in my car i went with 3:73's with my bower and i WISH i would have done 4:10's. On the highway with the gears i have now it is just over 2000rpm at 120km/h.

Not enough gear in my opinion.
An n/a car with a 3650 i would do 4:30's perfect gear for a n/a car but it is more towards the street car track car type.

I personally lost .4ths of a sec with 4:10's in my fox with a sticky tire and lost .3 with the 3:73's.

slicks with any gears over a 3:73 is a wild ride.

anyway hope this helps at all,
later shaved

 

I pull 1.7 60 foots all day off idle with 3:55 gears and M/T streets, just thought I would add to the confusion :biggrin:

4:10's will get you down the track faster then 3:73's
you need to know what you want, cause 4:10's are always reving too in the city and using alot more gas, if your turning it into a track car, go with the 4:10's, you will NOT be dissapointed, if your looking for a everyday gear with some kicks, I'd say 3:73's
Steve, I dont have any slips for you, but I'm at the track once a week and over time you can see what ppl run with certain mods...
Hope that helps!

 

For a daily driver, 3.73 will be just plenty.
