Obviously it would make a Huge difference if we are talking Overdrive or Std. Manual and Automatic. The Latter are both one to one in 3rd. but Overdrive is not.

The lower Power Six does require a much Lower (Higher Numerical) Ratio than a V8.
Most Eights are 3.07 or 3.31, and Sixes 3.73 with Direct Drive.
Probably 4.10 on a Six Overdrive and 3.73 on a V8.

It is Easy to check one, the Metal Tag with the Ring & Pinion Tooth count or actual Ratio is under a Screw on the Diff. Cover at 8:00.

I assume you know that 289 V8's and V8 Wagons have stronger Differentials, Dana Model 44 vs Model 23 or 27 in most Sixes and 259's.

In April 1960 Studebaker issued a Service Bulletin (354) that explained the various rear axle ratios available at that time:

(Sorry, I've tried to make these larger but it doesn't work. I can email them to you if interested send a PM).

I had a real learning experience on this subject when we got our Lark. It gave meaning to the expression "ridden hard and put away wet". As you can see below, it is a VI with overdrive and three speed transmission. For some reason it had a 3.07 differential. It could barely make it over a speed bump. I purchased a 4.27 from Newman and Altman (this was in 2001). The difference was amazing. The car has a 185 cu.in. engine. With that combination, it is a good highway car.

Perry, that's exactly the rear axle I ended up with in my '64 Commander with OHV six and 3 speed/OD. Tried (IIRC) a 3.73:1 and it wasn't quite low enough, and a Studebaker buddy of mine suggested a 4.27:1 ratio. Like you, I got a NOS axle from Newman & Altman (dirt cheap) and it's great.

I used to have a '61 Lark VI 2 Door Wagon with a Std. 3 Speed Manual Trans.
The former (Original) owner had pulled a small camping trailer with it, so he had changed the Rear Axle from 3.73 to 4.10, and it REALLY DID Scoot with that "Long Ram Induction Intake", 118 H.P. OHV 170 Six! :)

Well both are three on the tree.
Ii just picked up a parts wagon. And it has a V8. I don't know if it has overdrive in it.
I was just wondering if it will have a better rear end gears for my intended use.
I guess I'll have to check it out tomorrow when I get it home.

I didn't get to check it out, but I did get a picture of the parts wagon

The '60 Lark VIII, 4 Door Wagon is going to have the H.D. Model 44 Axle in it, if still original.

Yep the whole car is original, even the paint color. Supposedly.
Now to figure out what that v8 it is.... Sorry I am trying to learn as much as I can. But I'm s a noob to this studebaker stuff.

Even with the VI, would a wagon still have a Dana 44 - all that hard work and such?

My '60 Convertible that I no longer own was originally a 6 cylinder car with a 4:56 rear axle. A previous owner converted the car to a 259 V-8 but kept the same rear end in it. The car had a 3 spd with OD and it was a nice drivetrain combination.

Nope, sorry no Model 44 unless it is a Commercial use; Police Car, Taxi or H.D. Sedan/Wagon.

However, we ARE talking about 1959 and newer here, not '51 to '58's where all V8's had them.
