i have 3.73s...in my 87 gt.... i love them so far still havent topped put i and i have to drive 60 miles a day some times...not the werst 3.55 r good....but i love my 3.73s

anything over 3.73's will b to much so it depends if u want to feel the low end or top end of the cars ability, in other words you want a low top speed but get there hella fast or hav a good top speed and get there a lil slower but still in good time wit that 320 whp

im purchasing gears and not sure what ones i need to fit with the car...im mostly about low end performance but will need to drive on the highway for small amounts of time.. after this winter the car will be a 347 stroker with bigger cam and heads and all the goodies that make the stroker work well but im wondering what gears will work well with this set up...any ideas??

I would strongly advise against the 4.10's... I have the 3.73's in my 89 LX (just under 300hp) and 1st gear is almost a waste of time. Plus my top speed is affected. If you want to get to 100mph really fast and then be SOL then go with the 4.10's... I preffer to have a little more room to compete with the big boys out there. I think the 3.73's are better if you have lower hp like me. If you're running boost or have hp to spare than i'd go with 3.55's and let the motor push you through the gears. That's my $0.02...

I just put 4:10 gears into my car and love them. Revs just fine on the highway, and only uses 4th gear at the end of the 1/4 mile. 3:73's are the way to go if you really don't want 4:10s, but on the street you'll use 5th gear more which can help you in gas milage considering I never use to touch fith gear (before 4:10's) on the streets usually which left me running a little higher in the rpm's in 4th. I also only run a 26 inch tall tire right now.

I found that 4.10's got me into overdrive faster but I have an AOD.

So did my 3.73's. With my aod with extended shift points, at part throttle, it goes into OD just above 35 mph. But, I like it!

I have had 3 different gearsets (4 if you include 2.73s) in my car, a '94 GT. My first swap was to 4.10s. At this time the car had an AODE, and I REALLY liked them, save for expressway RPMs. They weren't crazy, but it was high, ~2700 at ~75mph. When I converted to a T5, the 4.10s were great at the track, but next to miserable (IMHO) on the street. Next came 3.55s. If someone has a bolt-on-only motor and primarily does street driving, these are just about prfect. As time went on, I drove the car less and built a HCI (heads cam intake) motor which currently makes 274rwhp. At this point, I went up to 3.73s. There really isn't a huge difference between these and 3.55s. Numeracially, 3.73s are really only about 5% steeper. So for T5 cars that are regularly street driven, I would stick with 3.73s or 3.55s, 3.73s maybe 4.10s for autos.

go with the 3.73s! I've had mine three years and I have a big commute, I drive mine daily (all year rain or shine) and the 3.73s are perfect, when i first changed them and got on the highway I noticed I had to rev higher than stock to go 65mph but its worth it. 3.73s all the way, and dont forget to change the speedo gear
