Depends on whether it's a Ford NP435 or Dodge NP435...but what Joe stated, above, is correct for the Ferds. Some Dodge NP435s don't have quite as deep a granny gear...it's like 4.56:1.
EDIT: and there is a very rare GM NP435, but it's a rare bird, as stated.
Actually Zac...it is just the opposite...the Dodge NP435 is 6.69:1 IIRC (I have several at home)...the Dodge NP445 is in the "4:1" range...the NP435 is what is called a wide-ratio tranny...the NP445 is a close-ratio tranny.
The NP435 is what you want under a offroader...the NP445 is what you would want under a "race" or street -only truck. Both are big block tough too.
The 445 allows use of all four forward gears (fully synchronized) unlike the NP435 which only uses 2nd, 3rd, and 4th (synchronized and helical cut) and 1st alone (unsynchronized and straight cut).
I believe dodge was the only one who used the NP445 in some of their trucks...and it looks identical to a NP435, but as I said, it is much like a car tranny in operation.
If you want to put a manual tranny in your truck, and plan on using it as a driver (daily or weekender) with any highway use, I think you're better off going with a conversion to a NV4500 5-speed. It has overdrive (albeit, not quite as much overdrive as your auto, at 0.75:1), but they came in late model 2500 & 3500 Dodges behind the V10 and Cummins and in front of the 241 t-case. I don't think it would take much $$$ to buy one, and then you'd have to get all the other "stuff"...bellhousing (may require an aftermarket piece), flywheel, clutch, clutch pedal a$$embly and hydraulics, tranny to t-case extension/adapter, etc. I'd think this would be a swap with more readily-available "conversion" parts, than would a NP435 swap, and you'd still have an overdriven gear.
