I just recently bought 85 k5 with extra 203 transfer case and turbo 350 .wanted to use it instead of 700r4 and 208 transfer case . What am i in for ? like 350 transfor durability aspect is this a good swap ?
 
Stick with the 208. Its lighter and has a lower range than the 203. Swap the 350 over in place of the 700R4 and call it good. Do a search on how to make this work.
 
What is the intended use of the truck?
Swapping to the 350, you are losing an OD trans that has a lower 1st gear ratio and of course the more fuel mileage friendly overdrive. As far as the t case goes, a 203 is a big , heavy unit, that is great if you are thinking doubler down the road, but if I wanted an easy 208 swap I would lean more towards a 241. :D
 
TH350 isn't stronger than a 700R4. It is cheaper to rebuild though.

x2 on keeping the NP208

If you really want to swap to the TH350 you will need a shorter front drive shaft and a longer rear.

Personally, I wouldn't swap it. I like the really low first gear of the 700 while wheeling and crawling. I also like cruising at 70mph with ease.
