I dont think the second case would like that very much

Well there goes my dreams again.....Syed 241 for me
Some of these combos are starting to be like the toyota guys and their 300:1+ setups. I have a 241/205 with 5.38's in my axles and with my 700r in first it's PLENTY low even with an auto. With a stick I'm sure it would "feel" even lower.
At some point I think it's just too much.
At some point I think it's just too much.
I am an SM465/NP203/NP205, 4.56's, on only a 38" tire and I wish I was lower geared in the transfer case. I think an NP241/NP205 doubler would be pretty decent.

I had pretty low in an early bronco I built 181:1, it was good to have at times for crawling in Colorado. But it has its drawbacks as well, to much gas pedal equals broken parts. I really would not have gone any lower than that, that was crazy slow at an idle and the brakes would not hold it back.
That's almost exactly where I'm at with my setup (175:1) and my brakes won't hold it back either.
Thats nuts. 4lo in my 208 is like almost too low for my liking. I mean i shift into od in my driveway.... Lol. You rock guys and ur goofy needs for super low gears
I know nothing about T cases and all the gear ratio, T case talk makes my head hurt like a tumor is back in my head 
. I've never worked on a T case but would love to know all the inner working of one, but I NEED to see it first hand not read about it. I'm a visual guy, I need scamatics or beautiful color pictures starting at 1 and ending at xxx, then bolt it in.
I know exactly what I want to have as far as options in gear ratio and drivability on the road. I also know I want a bad ass setup off road, but I have no idea how to go about figuring this all out. I just want to hand my case off to someone who knows what their doing and give them money and get it back and it be correct and what I want period. I'll build the bad ass crossmember(s) but this T case stuff is like electrical to me, I just don't get it damnit.
I'm going to be runnung a mildly built TBI 454, I currently have a 350TH married to a 205 in my K5. I want a 4 speed TC with all the ubber bad ass 32 spline shafts, cause I want all the options regarding TC gear ratio available. I'm running 38" tall tires to start with, will end up with probably 42"s at some point. My axle ratio is 4:88's. I want to run a reasonable RPM at say 65. I was convinced I wanted an Atlas till now. I dig the ORD Magnum setup and the lower cost vs an Atlas.
My questions are, Do I have a good axle gear with the 4:88's?, or is it too deep for the size tires I have and eventually will have? Do I just yank the 205 and ship it to ORD and get it back all setup with the Magnum and be done with it? Should I run a TH400 behind the 454 instead of the TH350 trans? I have a TH400/205 out of my crew cab I can run. Is that the better setup? I also have an 4L80e trans I though would be the best option backed up with an Atlas. Now should I run the 4L80e and the Magnum setup instead? I thought the over drive on the 4L80e would compensate for the 4:88's.
I also have a 241 TC, but I have always herd a chain drive Aluminum case is weak. IS the 241 a chain drive even??? I like overkill so I like a cast iron 205 for it's brute strength. I really have to more room for tranny's, T cases's, big block's and axle's. PLEASE tell my the correct setup is the 454 with the 4L80e mated to the Magnum and my 4:88 are perfect for 38"s to 44"s with the OD trans.
I would like the keep the TH400/205 for my crew cab as it's the stock setup. I can sell the 350/205 or keep it for some other project some other time. What say you experts??????

You don't have to mash on the throttle when you are geared way down.

Oh, I read all that yesterday then didn't respond. 
To me it sounds like you're a perfect candidate for an aftermarket case. If you don't mind spending a little more look into an Atlas or Stakk.
You mentioned freeway speeds but that doesn't really come into play with the case gearing so you just need to be mindful of your axle gearing. Your 4.88's and a 40" tire in 3rd gear at 65 mph puts you around 2,600 rpm. Not bad for a truck that isn't built to drive down the freeway.
Yes the 241 you have is chain driven in stock form. The 241's are good cases, they ran them behind TONS of '88-'98 chevy trucks and suv's and a bunch of dodges, even behind the cummins/nv4500 combos. That being said the part you use out of it if you were to build it into a range box that goes between your th350 and 205 is just the 6 gear planetary gear set. So you don't have the chain anymore.
Hopefully that helped, if not ask again and I'll do my best to explain what I can.
All that being said I'd first decide what you really want to do with the truck. There are plenty of guys wheeling some hard trails without all these new fandangle geared to the moon setups. They probably work harder but they do it just fine and with a lot less money wrapped up into their rigs. If you plan on moderate trails maybe a simple 241 would work for you. It's almost 3:1 from the factory and is super plentiful. If you plan on crawling and want absolute control start gearing down... go as low as you can go.

An NP241 transfer case is an aluminum case, chain driven transfer case. They are not as weak as you would be led to believe.
With 38" tires, 4.88 gears would be okay, with 42" tires and overdrive, they would be a little high (low numerically) What axles do you have? What kind of off roading do you do (or plan on doing)?
Call ORD and just talk to them. They are helpful, and will build you whatever you need.

Axles are D60/14FF like everyone else for the most. I want a rig built for hard core use, and want to be able to wheel it that hard and have it survive if I DO wheel it that hard. I have cromoly 35 spline axles for my D60, will probably run an air locker up front, have a Detroit locker in the 14ff, and want to upgrade the stock axles there too. I bought a 35 spline locker for the rear so I'll be running 35 spline aftermarket axles out back as well. I know 300M 35 spline 14ff axles are available. I love overkill beef

GGGGRRRRRRRRRR............thanks ORD.......
just finished up with a 203/205 doubler a few months ago.......
and NOW you come out with the magnum......
do you take trade ins ??

I have been waiting.... patiently. For a long time to get my money together enough to buy a 241 doubler kit. Got the money together, call ORD, and nope, sorry. They don't offer it, and don't know if they ever will. To much time and money invested in the magnum box for the rich folks. Does anyone know of ANY body else that offers the parts, (shaft, shifter, anything) for me to piece one together to work with a figure 8 205? ORD is such a let down.
It's not too much money invested in anything, it's time. We are expanding and our day-to-day business is booming, our machine shop is totally overworked with day to day operations.
That project was unofficially announced and never made it on the web page, as mentioned it is on hold for an unknown ETA.
We do have lots of parts, shafts, plates, etc. if anyone has interest in that. Until we have more machines/people/shop space that may be the status for the near future.
