A833 OD 340 4x4?

I'm not a truck guy, But I have never seen it in a Dodge. Someone here just mentioned seeing it in a chevy pick-up, so you can pirate that whole thing. But NONE of the chevy gears will mesh with any Mopar gears. So you would have to swap the Mainshaft and housing onto your Mopar box.
How would that work?
Awesome.
The normal 4-speed for this application is the NP435, but the splits in that box are real truck splits, meaning grain-truck on soft ground type splits. Not suitable for hi-rpm useage. The ratios are;
4.78-2.39-1.37-1.00 and
splits of .50-.57-.73
There is another Dodge ratio set, but it's even worse.

Somebody mentioned the NV 3500 5-speed. This has excellent ratios, but IDK if it is available with a transfer case.
The ratios are; 3.49-2.14-1.38-1.00-.73od. With
excellent progressive splits of; .61-.645-.725-.73
IIRC it is rated for just 300ftlbs tho, so forget the stroker. The 5.2M even makes more than 300......

But I got a question for you; keep in mind I have no experience in off-roading.
Say yur having a good time in Second gear in soft stuff, and suddenly the going gets tough in a hurry. How will you downshift fast enough to not get swamped? It seems to me that the instant you stab the clutch, it will be all over; am I wrong? It seems to me that this is where the auto and hi-stall would shine.
