Rear axle ratio? 77 V6/5spd

Postby marco_1978_spyder » Sun Sep 17, 2006 9:14 am

Anyone have an olds brochure or the "standard catalog of oldsmobile"
handy?

Just trying to verify the rear axle ratio this combo would have come with.

2.73 or 2.93?

I have the 78 book and it says the gear is 2.93 for the 3.8/5 speed combo. Interestingly the crankshaft revolutions per mile are 2604.8 with an A78-13 tire.
