2:73 to 3:73 gears in my stock 88 gt convertible.

[aray176]

doing the gears in my car this weekend and i'm wondering what performance diffrence to expect. first time messing with foxbodies so i'm a bit in the blind. all i have now is catback flows and hurst billet plus shortshifter. any input will be appreciated.its a 5 speed car.

it is said that adding 373 gears feels like adding 40hp on the bottom end of the power band

I would like to put 355 or 373 in mine.Iheard the 373's are better for convertables and the 355's are better for hardtops.I dont know why..this is what I heard.anyone have any input?I have a hartop and am wondering wich ones I should go with.I want to keep it and everyday driver not a 1/4 miler.Thanks!

3.73 are a comfortable enough street gear for an auto. for a 5 speed, 4.10s are recommended. but that is if you want a much faster car. id stick with the 3.73s. as for the install, make sure you have everything you need. (rear end rebuild kit) because as long as you are in there you might as well freshen everything up. new bearings, spacers, etc... it also makes the install easier. as for the speedo gear i think you may need a 23 tooth but dont hold me to that. check with ford racing.

i just picked up 373s myself i wanna put disc conversion on it and a rebuild kit before i even throw it up

Going from 2.73 to 3.73 in an auto is going to feel almost as good as adding a SC with 6lbs of boost to put in perspective! I installed some in a my cousins 88 LX coupe and it was night/day difference. I'd guess around .5 gain the 1/4 easy. I know with 4.10's in my 89 LX I used to have it was .9 in the 1/4 gain with AOD.

i was checking into gears myself, since my car is not a daily driver would i benefit more from a 410, or is it overkill and should i stick with my gut for the 373? i think my car is 308 stock. also adding underdrive pulleys( had them for a while but never installed yet) will i pull out of the garage smiling large?? i hear they are the best bang for the buck but just wondering if the pulleys combined with the new ratio will yield a much different feel from the car power/acc wise-

Intake / Exhaust and gears are the first mods i suggest to anyone. Whats the procedure you use to determine exactly what gears you have? I know you jack the rear of the car up and mark the tire and driveshaft and count the rotations but what is the ratio's of turns / gears?

 

[white94svt]

i was just assuming that the car has the stock 273 or 308 because im the second owner and the car was never modded, I have all the reciepts
