will it be strong enough

hi i was looking under my 89 zook tonight and had the idea that i might be able to fit the transfer case fron a lj80 infront of the original case im curious to know if this has been done successfuly and would the lj case hold up
Yes, the case will take the power, The real problem will be where to fit it and what it will do to your high range gearing.
Some quick guesses indicate your high range gearing will go to at least 2:1... not very different to the low range gearing you have with stock transfer gears. This would pretty much rule out road use.- top speed would be around 80km/h
I have looked into this before and fitment is an issue. The lj80 case has at least 200mm of drop from input to rear output so the angles will get all wrong.
Lots of ideas like this used to be kicked around before transfer gears were readily available and affordable.
It's probably possible, you could clock the LJ case over to raise the output and clock the sierra case to make it line up but there would be masses of work in it... including lots of work to the floor, and the oiling and shifting of both cases.

thank you for your input my other main concern was what it would do to my high range gearing i just checked it out again it is 115mm between centres of the input and the rear output shaft the high range ratio seems to be about 1.4 to 1 so im guessing that would decrease my high range ratio by 40% feel free to correct me if im wrong also im running 32s with wt diffs im only considering this conversion as i have all the parts required and it should be easy to return back to standard
if it's 1.4 (I think it's a bit more) yep, that's a 40% reduction over what you have, so to keep stock gearing on the road, you'd need a 40% bigger tyre.... which is nearly a 37". your low range (combined) will be up in the 6:1 -7:1 range....
for the work, i vote go with transfer gears. It might even be cheaper - the'red be a minimum of $600 in the driveshafts to make it all work, you'd want to rebuild the 80 case.
Gears are pretty cheap now.
