Yup. For five speeds in a K series with a big block the NV4500 is pretty much it.
A Ranger OD gear splitter or Gear Vendors overdrive unit on the SM465 are other options. You actually get 8 forward gears with this setup but there's likely overlap.
The price of all three of the above end up being pretty much the same.
The NV3500 is a five speed, and can be had in 4x4 dress, but the torque capacity peaks at 290-300ft-lb... not enough for a Big Block 400 say nothing of a 454.
The S10 4x4 T5, rated at only 250ft-lb, doesn't have anywhere near the torque capacity for a mildly built smallblock, stock 6.2L Diesel, or even a 250 I6.
The NP440/A833 MM7 doesn't quite have the torque capacity for a 454 and, even tho it's an overdrive trans, it's a 4 speed.
