i'm lookin at gettin a 00 gmc seirra z71 and i was just curious of what the t/case with the auto 4wd option can hold up to cause i was thinkin about maybe putting something like a 408 stoker in it and usin it as a kinda part time AWD.

 

They seem pretty stout. Mine is holding and I think one was taken to ~1000hp (Parish?) without issue?

 

Jim had the HD manual TCase. From what I understand, the autotrac's are junk, but I've never broken one (or had one for that matter )

 

welp no need to worry about my plans now cause the deal i was lookin at fell through :/
