Whats the stock gear ratio on a 88 iroc

Dumb question.. but i don't know :mad: heh thanks

depends on the tranny but it be posted on www.thirdgen.org

well the 350 only came with an auto.

those were some strange rear...australian or something i think. with strange ratios.

2.77s or 3.27s i think. the higher ratio came with the g92 package, wihich i think ment you got 4wheel disc brakes

1988 350TPI & Auto came with the BW 9-bolt limited slip. A 2:77 was standard and 3:27 was a opton. But most were 2:77's and all required rear disc brake option J65.

Check your RPO codes.
