It's the front diff/axles you should be worried about with the F/I. Dumping the clutch from 4.5k (slipping it a little to keep the revs up) will destroy your front drive train. You will need an upgraded clutch to be able to slip it off the launches so you don't bog. That is how my xi ended up RWD. I ruined my front diff and got sick of tearing the front end out of the car to fix stuff. The T case will be fine, the front/rear half shafts will be fine. But that front diff being up against the block gets way too hot. Going F/I is one thing, driving the car the way it should be driven without breaking stuff is another. GL with whatever you decide to do.
