I got the gears from a member

[oldkimmer]

8 on the pinion, 41 on the crown. 5.13 ratio. Looks to be Sheifer gears. Has a spool. I presume this is equivalent to a 742 case. Thanks Max1196. Kim

 

[toolmanmike]

Huh? What are you getting at Kim?

 

[oldkimmer]

Just showing off my new to me parts. Kim

 

[Garrett Ellison]

Yes, early equivalent of the 742 with 1-3/4 pinion.

985 case that's new to me. I have a 657 case with 3.58 gears from a 58 1/2 ton dodge truck.

I'd like to see that 8 tooth pinion side by side with this one from my 2.21 gear set

That is the early 741 case.

What in the world did you find a 2.21 gear in?!?

What in the world did you find a 2.21 gear in?!?

89 Fifth Avenue AND 1980 Diplomat. Don't worry, I switched to 3.21

Previous 0-60 was measured with a sundial

Yes. When I rebuilt it all the bearings were the same as 741.

As 17 year old I ran 5.13's in my daily driver 340 4 speed Duster.
The things we did when we were young.

Had a buddy who ran 5.13s in a 57 chevy with a 283 and a four speed. I thought he was crazy. I was only running 4.56s behind my 350/4sp.

 

[SGBARRACUDA]

If that ain’t enough, I have a set of 5.38’s.

You got a slant 6 dump truck too?

Hell I just finished building a 5.57 with a spool for another member.

 

[Darter6]

Locally about 15 years ago we were servicing a Dodge 1 ton dump for Hoover Dam and it had 5.57 dana rear to pull the hill form the bottom of the dam to the top.Automatic to boot.

I'm sorry to have to say the C word. A kid in high school had a Modified production Camaro with 6.17's

That is a factory defect. The one on the right is a ring gear with a stem on it.

I stuck one of those diffs in my 51 pickup, not realizing the gear ratio. It would go 30 mph at idle in first gear with the 265/75 16’s on it. Doubt that 80 hp flat head would pull in 3rd gear.

We took a 170 out of a buddies 67 Valiant because it could not climb a grade. We dropped a 225 in and it did not help much turned out he had a M-body rear end in it at 2:45:1 or a 2.21. Ridiculous!
