You would have to either make or find a new or modified tailshaft housing that can mount the transfer case. I don't know of anybody offering that right now, but that doesn't mean much.
So, mounting the Borg Warner 4472 transfer case (the one used in the Sy / Ty / AWD Astro / Bravada) or any other transfer case isn't impossible, just very difficult and expensive at this point.
The other concern would be transmission strength. With all that traction, the clutch and transmission would take a beating. Hopefully, the clutch would act as the fuse and keep you from breaking transmission parts. You'd probably want to do every upgrade on the trans you can (Viper this, HD aftermarket that, whatever).

Yeah, I think that would be a kick *** conversion. I also see the GM 4.2L Straight 6 being a potent turbo motor in that thing too, but pretty hard to cram a straight 6 and the AWD out of a Trailblaizer SS into the a WRX.

Yeah, thats pretty much the issue you run into.
I would expect that some of the truck manual transmissions would bolt up, but most of those have a granny 1st (and you couldn't shift quickly if your pink slip depended on it!) I'm not sure if the Richmond Gear 6 speed has a Tcase tailshaft available (but thats still a high dollar option). You could probably do a 4 speed manual without trouble, but then you give up overdrive gears. I don't know that there is a good 5 speed choice either.
Stock, the BW4472 bolts up to the 700R4 / 4L60 / 4L60E / 4L65E. Sadly, the trans isn't really all that stout. Maybe the new 4L70E package that is coming out in the '06 Trailblazer SS will be a little better, but......
The path that I intend upon following is using the 4L80E (or a 4L85E if I can find one for reasonable money). Sadly, that requires a replacement output shaft (modified to provide 27 splines vs 32 spline stock) which means you've got to completely dissassemble the trans. Once you do that, at least you'll have a 4 speed auto. Or you can run a TH 400 with a GV Overdrive (but that's probably the same or more money as a 4L80E).
It all boils down to there isn't a cheap solution. What a suprise.

I love the thought of a torquey LS1 6.0L in an all wheel drive astro van, that is too cool! Any pics?

Yeah just the other day I have decided on going with the 4L80E but I thought the bw4472 T-case would bolt right up to the tranny. maybe you could give me a little more info on what I need to do since you said that your doing the same thing. PM me if need be because I have a few questions about it.

Is there any chance that the Trailblazer SS will eventually be offered with a T56? I remember the early stages of development with that option package and they were experimenting with a T56, AWD, and twin-turbo on that straight six. If nothing else...what about a venture gear 6 spd? They offered those out of dodge cummins trucks and obviously you can get them with a transfer case. Also, you should be able to get the right gear set with them since Gale Banks and company experimented with that on the salt flats a few years ago, though in 2wd. configuration. At least you'd be able to source a junkyard gearbox, and figure out what you need to make the converstions. Just a thought.

I hadn't thought of running it as a divorced setup. That would work, but take up a fair bit of room. Reason I hadn't considered it is that most vehicles I've been considering don't really have the room for that. And the solution from Turbotime is available.
I have no idea if GM will make the T56 available in the Trailblazer SS. All I know about it is from the press releases. I haven't seen a price as yet. Personally, I'm guessing mid $40's and not expecting to see incentives on it (like employee pricing or anything).

Consists of a replacement transmission output shaft (with 27 splines) and an adapter to mate the tailshaft mounting pattern to the transfer case (at least thats what was explained to me). You do have to completely dissassemble the tranny (the output shaft is one of the 1st things in and last out when you take it apart).

AWD option in the news forum listed it ~42k, fully trimmed.

Oh, I'm with you there. I don't think I'll ever spend more than 25~27k on a car/vehicle ever unless I hit the lottery. Obviously that's price of the car, not withstanding additional modifications

Hey, you never know until you ask or try right? Yeah, I know what it's like to shift my Dad's 97 Cummins 5spd (4.10 rear
). The throws are long, but that gearbox has over 50k miles on it (knock on wood) it's running great.

i dont know that a LS1 will fit but Lexus has V8 AWD cars now. if they still use the same basic UZ-FE engines, and they probably do since they are proven, then dimensions should be similar

sorry about the consecutive posts but i was thinking something else that would be cool, take a T56 and modify the head of the tranny just behind the bellhousing so that the transfer case is there and drives off the front of a custom gear shaft, then run the driveshaft as close to the engine as possible with the front diff housing bolted to the engine like an accessory, you could run the front driveshaft jointless and it would move the tranny and shifter back only a few inches. just a thought
