gears question
I have the 2.77 posi-rearend in my 88 Iroc, and I was told this was a BW unit
, weren't BW's 3.27's? Also I was told switching it to a 3.42 would be hard if not impossible. Can anyone help me out and shed some light here? Thanks.

Common factory 9 bolt borg warner ratios were 2.77, 3.27 and 3.45. Uncommon ratios were 3.08, 3.70 & 3.73. Ratios that are offered at www.9bolt.com are 3.23, 3.45, 3.73 and 4.10.
Switching to a 3.45 ratio is easy. It requires a series 3 posi carrier, a 3.45 gear set and an installation kit. Package price is 785 +s&h. More information is available at www.9bolt.com
