Numericaly high are low gears, and vice versa. I think I've seen as low as 5.57, never really looked hard tho. High gear would be 2.76s, I've never seen higher than that if they exist.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I thought 5.57's were the lowest! What make are these? any pics possible. More details please. I needed a lower set for my circle burner & 5.57 was all I could locate. I ended up using a 9" furd with 6.20's

No, NO ....  ...on ALL counts ! 
A LOW gear ...is a SHORT gear. A high gear is tall, steep and BIGGER. And the steepest gear ever offered for the 8 3/4 was a 6.17. And the SHORTEST would be either a 2.41 or 2.45.
NEVER seen one of those though.

i know he does.
A low gear is a steep gear is a high number (like 4.11's)
a high gear is a tall gear is a low number (like 2.76)

when you put it in low, you drop it into 1 which is the highest numerical gear in the tranny. the lower the gear, the more umpf you get.
do a google on 'what is low gear' or low gear ratio

Yes 440, you have it backwards... at least in terms of a car. It's easy to get confused by it. In automotive circles, gear ratio and the description are tweaked...lol. The higher the torque multiplication, the lower the gear in terms of transmission gears you're in. First is a "lower" gear than 2nd..etc etc etc. This is carried over to the rear axle too. You're technically right with a lower gear ratio being 3.23:1 vs 5.13:1 because there's less turns of the drive gear vs the driven gear. But in automotive circles, it's not a standard way of describing things.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

its simple...do you take off in low gear or take off in high? in a normal 4 speed 4th is 1-1 but first is way lower and has a higher # ratio

The catalog I quoted from was from 1974. I don't think they have or wish to sell any of that stuff. That was 30 years ago.

ok i went and dug the 500 pound chunk out of the shed here is all i found
its a 742 case with a big on the side of it
has 43 gears on ring and 7 on the penion(sp?)
also has like some kind of bright shinny line across the ring with 184 and looks to be a j etched into it then 5010 h then looks like a apple shape then 7 r 8620 what the heck does all that mean?
i took these gears out cause the penion nut backed off and thay strated to make a houling sound one night so next day i swaped them out

43 teeth & 7 teeth is certainly 6.14's. The #'s dont ring a bell. A damaged/howling set is no sweat on a circle burner because the open exhausts from 20 cars is deafening.

It does take a different mindset because you'd think that'd be WAY too low but it's perfect(.4 mile high banked dirt track) 360 9-1 CR 2bbl by class rules & at the end of the straights it is still pulling strong at over 6400. Those Hughes cams are awesome.

I swear I have a 2.72 gearset in a 742 housing from a very early '60's Chrysler. The older pre '60's cars had some unique gear choices, didn't they? I've seen some odd ratios (example 3.36).
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

Robert, I could send you a picture of it, but there are alot of mopar parts in the way, getting to it. Do you really want me to dig it out? The numbers are stamped in the gear set. Every time I've had to dig through that area of the garage, I look at the ratio because I too, find it hard to beleive.
