i have 4.10 in the rear dont no my spedo has not been fixed sense i put them in

 

About 2500 rpm at 80 mph with 3.42s.

 

are you looking for quarter mile gears, or gas mileage gears?

 

Only gear ratios available for BW 9-bolt rear axle are:
2:77 2 series carrier
3:27 3 " "
3:45 3 " "
3:73 3 " "
Also these parts are very expensive. So it makes no difference what other people are running if they are 10-bolt axles.
Note! irocz8957 ...read my reply to your first post.

 

Damn,I forgot about the 9 bolt being in 3rd gens.I just read a post on here somewhere about a guy who just replaced the gears in his 9 bolt with 3.73's and I think he said he paid like $310 for the ring and pinion.

 

I have a 5 speed and 323's an am runnning 2000 rpm at 76 mph.
A friend has a t-56 and a 4.10 and runs 80 at 2000.
hope it helps, if you have a stick

 

3.23's before the tear down, 1750@60.
I personally don't do a lot of interstate driving in my Roc but my 3.73's should add about 600-800rpm over my current 60mph cruise in O/D.
The best "compromise would probably be 3.42's(as close to a 3.50 ratio as possible), but I want stronger 1/4 mile acceleration and maybe later add 28" tires to the rear.
