Who knows T-cases??
Just curious, im thinking about swapping out my weak, chain drive transfer case in my f250 for a Dana 20 or 21 with solid gears. Will the case bolt directly onto my 5 speed or will it require an adapter?? Is there another case that has solid gears that might be more up to the task of handling my 460? I HATE

Unless the chain is shot in your existing case, there is absolutley NOTHING wrong with it, your 460 will never show it the punishment the diesel guys show them .
If you want to run headers on your truck, you cannot run a 205, the front output is a good 3-4" closer to the centerline of the truck, and noone makes headers that will clear the front driveshaft with a 205 installed.

besides isnt a 20 or 21 a single speed transfer case? If you are worried about the chain breaking then see if the chain is stretched. Most of the time that chain will outlast the truck unless you drive around the pavement with it in gear. Doing so will stretch that chain faster than anything. If you are dead set on replacing it, use the 205 it will bolt right up minus some bracket mods to get it to work with the transmission.

the np205 is one of the strongest t-cases out there, and with a simple shift rail mod can be twin sticked
if you think must change your case then go 205, but id just put on a new chain on yours though
headers will be a issue with the 205 as already mentioned
i have L&L headers on my 460 swap---96 150, c-6, 205
not sure if they would work for you but L&L makes alot of specialty ford products and might have something for ya

Not true! The later model F-250s and 350s ('96-'97) came with BW 44-07 witch are about the same size as the 13-56 but HD. I would swap in one of these. Still chain drive but stronger and no fab of parts. You'll just need the rear driveshaft out of the BW 44-07 truck because it doesnt have a slipjoint out of the T-case. Its a four bolt flange just like the pinion flange on the 8.8 rear diff. on an F-150.

I prefer the strength and reliability of the gear drive. chains are just a hastle. besides the gear drives are easier to shift. unles I get it just right, the gears grind in my curret t-case. that's why I was wondering.

If you are shifting from 2 hi to 4 hi without locking in the front axle you will get a grinding from time to time on both the gear and chain drive t-cases, unless you get them just right.
If you are shifting from 2hi to 4 low or 4hi to 4 low you will most of the time get a grind with both the chain and gear cases. It really is a practice thing and these cases are not really synchronized like a manual tranny to allow for the grinding not to happen.

then id look for a 205 out of a ford, gear to gear, and can twin stick it
used (working still)should be 200-300
and jeffs bronco graveyard has rebuilds for around 700
but you will need to fab custom mounts and have a driveshaft--s made

Auto hubs are why you're getting grinding, there is no shifting on the fly at all with those, you even have to be stopped to go to 4-hi.
As for a 205 being easier to shift, my DD has a 205, and there's no way it's easier to shift than the 1345 in my wheeling pig.
