Question on a Cutlass I found.
Reading the RPO’s (if I am reading them right) it’s a Canadian built 87 with a 305, 4 speed, it says the rear end is a 2.57:1. It has the build sheet, where I got the RPO’s but I can’t decipher those upper numbers in the blocks.
STE - PLANT CODE- ST THERESE, PQ, GM OF CANADA
GM8 - AXLE, REAR,2.56 RATIO
MW9 - TRANSMISSION, AUTO 4 SPD, THM 200, CONV CLUTCH
LV2 - ENGINE, GAS, 8 CYL, 5.0L, 4BBL
KM9 - MANIFOLD, INTAKE(ALUMINUM)
Using an online gear calculator, it shows 1656 rpm for 70mph with the stock 195/75-14 tires installed. Doesn’t that rear end gear sound kind of tall? Or is this a boat they built for emissions.
