A-833 2.47 1st gear change to 3.09

3.09 gearset will swap into your cases without any other modifications. I run this gearset in my 72 Demon, with 3.23 axle and 27" tire.

Maybe I missed it, but did you ever answer the original question? Can he swap the 3.09 gearset into his case?

I saw the comment that you wouldn't, but that wasn't the question.

Dan Brewer chimed in and said it would. I’m going to trust him as a solid source. His comments have been the most helpful. A guy that is in the industry. He’s in the manual trans segment of the industry. He has a real world report on 3.09 / 3.23 A-bodies.
It’s not just bias on what I wanted to hear but it’s because it shakes out in the math (no matter what your power plant is or makes). The gearing is better for that rear gear and drivability.
This is all about driveability. I’ve talked several times about parking lot manners. 3.09 helps. I’m satisfied *enough* with the low comp 340 to do the gearing first.
So, now I have a plan. Or a multi-pronged approach. Try to acquire a case like mine (bearing size), get the Commando gearing and start getting really familiar with it. Then, when weather is crappy rebuild my case. I’ll do the ball and detent cover at the same time. I think I have to modify something so I need to learn that too.
