were there 2.77 gears put in the borge warner rear disk brake 9-bolt rear ends?? or were they all 3.27

The car is an 89 camaro Iroc

Thanks

 

B-W 9-bolts with 2:77 gears all had Disc Brakes. There are more 2:77 then 3:27 9-bolts out there. These gears used only on 350
TPI cars.

 

I've got an 89 IROC with the 5 speed and I have a 3.45 gear in my 9 bolt. Is your car an auto or a 5 speed? If the rear end cover has never been off, there will be a tag attached to one of the bolts that will tell you the ratio in the rearend.

 

The post was for gear ratios (2:77 & 3:27) used with a 350 (Auto)
engine only and not for the B-W 3:45 which came ONLY with the 305(5-sp). And they all used disc brakes.

AGAIN I WILL SAY, THE ONLY FACTORY STOCK BW 9-BOLT AXLE RATIOS USED ONLY ON 350 TPI ENGINES WITH AUTOMATICS WERE 2:77 & 3:27 (which was a option)GEARS.

 

There were also 3.70 gears for the 9 bolt.

 

All the 9 bolt info you need is at www.9bolt.com
