I have a 87 GT Convertible. 5.0, CAI, BBk headers, Off Road H pipe, Flow Masters the rest of the way back. The car is an automatic with stock 2.73 gears. The car is a dog at take off. What gears do you think I should go with. I've been thinking either 3.56 or 3.73. What do you guys think?

 

My friend has 3.73 and the stang feels good its also an automatic... it runs good on the street and freeway

 

i have a buddy with 4.11 and a shift kits and this thing is bad to the bone but............gas milage is well.......there is none really lol

 

4.10's for an auto

 

No less than 4.10s.. 3.73s will leave you wanting more.

 

i have 4:10s in my 5 speed and still pull 18mpg on the interstate, i would definitely go higher then 373

 

3.73's for a stick period unless u like to shift even more like a madmen its just not necessary for a daily driven vehicle especially if u put any nos or boost to it later u will not want that steep of a gear with a power adder for the street or track as u will just blow the tires off.

if u are planning a little boost or something i would stay in the 3.55-3.73 area

 

i only put around 5-7k miles on my car a year so im not to worried about it, it used to have a procharger on it

 

and with a procharger i bet u would just light up the tires and shift out of 1 st and 2nd real fast i know ive ridden in a few supercharged stangs with 3.73's

 

I have a shift kit in it now and as of right now I do a lot of city driving but, might be moving about 6 miles from the city. The next upgrades I would like to do to it is a 65mm throttle body and egr spacer, gt40 heads and a different intake. I don't think I want to do a cam because I would have to switch to mass air and that sounds like a pain but, if I go through and put heads and intake why not do the cam while I'm there. Right now I want to do gears and go from there.
