Uhhh, this was after the fuel crisis! The highest ratio was 3.55 by then according to the 1974 dealership data book. And the 3.55 was only available with a sure grip which is code D91 (high isn’t on the fender tag).Some A code designate axle ratio and size with options such as a performance axle code or a tow package code. You tag doesn't have any of those code so in your case, no.
It probably has an 7.25 rear with either 3.55 or 3.91 gears. Can't remember what ratio came standard in /6 cars. In /6 trucks it was 3.91
The GG white book shows a 7.25 3.55 for 72 but not for 73-4, just 3.23 and 2.76Uhhh, this was after the fuel crisis! The highest ratio was 3.55 by then according to the 1974 dealership data book. And the 3.55 was only available with a sure grip which is code D91 (high isn’t on the fender tag).
The standard ratio on 225 Duster with a torque flight was 2.76 with the optional ratio being 3.23.
Trucks were exempt from fuel economy standards that were coming in so that’s why they were still available with 3.91 gears!The GG white book shows a 7.25 3.55 for 72 but not for 73-4, just 3.23 and 2.76
Wish I had a 75-78 book. Wonder what gears came in the 76 A /6 833OD? First American car to get 31 MPG hwy.
I had a 75 Dart Sport /6 3 on the floor but don't know what gears it had. Felt like 2.76 as it was slower than frozen snot.
I've had /6 trucks from 73-87 with /6 and all had 3.91 gears in either a 8.75 or 8.25.
Yes I was just making a useless point that they still made a 8.25 3.91 after 72, just not available in cars?Trucks were exempt from fuel economy standards that were coming in so that’s why they were still available with 3.91 gears!
That’s the loophole AMC used when they came out with the 4WD Eagle.
