Mark Stielow pulled it off, but how????

[Kenova]

GM is also using an AWD transfer case behind the 4L80E in the full size vans, although I've been told that the only difference between it and the Silverado SS Tcase is the size of the input shaft.
You should also check out ATS's new spindle. It uses Corvette bearing hubs, so it may be possible to use the rear hubs on the spindle for AWD.
I believe the bggest hurdle to overcome would be the packaging of the front diff.

I've followed this thread and have some ideas to share.
Today I would use a Tremec TKO-600 and the GM149 out of an escalade or GMC denali
and make something like Stielow's mod. on the tailhousing.
Maybe someone outthere have readymade tailhousing for tranfercase adaption??

Hey Ken, mine's still coming along fine.

I would think the needed space underneath the car would be a problem.You could only clock the transfer so far before you got into front driveshaft trouble.Been contenplating an AWD setup on a g-body using somewhat factory pieces...since the s-10s are so interchangeable on most front susp.pieces.I would like to make this conversion with mostly factory pieces because of ease of replacement parts.It would suck to break totally one off parts away from home

[ProStreet R/T]

I've been putting a lot of thought into this and honestly if you want the car LOW it will not be an easy setup. You WILL have to raise the floor boards, not only for drive shaft clearance, but for the t-case as well, they are BIG and will be right under the driver seat.

I have found a way around this but requires some extensive mods to the t-case. But if done right you could run a d-shaft under the car with no problem what so ever, and put the thing in the weeds.

quit looking at cars for the answers

Or just get crazy and build a lambo-esque 1st gen, put the motor in the rear and you have tons of room for the front drive line.

I was talking to the guy that was using the escalade bits last year. I kept telling him AWD was a horrible idea, etc etc... then he showed me his plans, and I shut up.

I still don't think AWD is practical (after owning, and breaking 3 trannies in my subaru), but if you're as mechanically inclined and connected as this guy, I thiink it could work.

Here are pics of my AWD project. It is a 56 Chevy. I am using a escalade transfer case and will use a 4l80e transmission. Front is a S10 4x4 diff.

Anyone finish a AWD project yet?

A good donor candidate is new trailblazer SS.
The Trailblazer SS has a 400hp LS2 V8, AWD (not 4WD) auto tranny, tons of aftermarket options, full programmability for the ECM and TCM, and the front diff shares space with the oil pan.

[Jonesy_SA]

Anyone found an affordable 5/6pd and transfer case to handle 600hp in light vehicle. TLast post was oct 2005, someone must be finished :-)
thanks

[Steve1968LS2]

Wow, this thread keeps coming back from the grave. lol

The new TR6060 should be able to easily handle 600hp.. oh wait, you said transfer case ;)

There are some t-56 awd units out there. Most are homemade, but I did hear a rumor that Callaway Cars has developed a 4wd/awd tail housing for the t-56.

A few links:

I've exchanged e-mail with the gentleman who authored the below posts. He has shared pics of his set up with me, but without his permission I don't feel comfortable sharing them.

BTW, a little birdie told me that George at Rockland Standard Gear has been involved in putting together a couple awd t-56 units.

A new tail housing casting would be ideal, but I think a Viper tail housing would move the shifter far enough forward to allow for modifications similar to what has been done in the above syty.net links. Being a Syclone owner, I would like to see a t-56 with custom tail housing that would bolt in the place of the 4wd 4l60e/700r4 which would allow the transfer case to remain in the stock location. With the resources available here at pro-touring.com I think this could be accomplished.

Whoever does the mock up on this new production part make sure it will allow several transfer cases to bolt up, such as the BW-4472 (Syclone, Typhoon, Bravada, Astro), NVG-149 (Silverado SS), and NV-120 (Trailblazer SS).

Thanks for the links, i had read a few before and found the syty.net site helpful. I checked out the hotrodders links but it says he has only posted 3 messages. Has he compleated much in the project? There was nothing on there so not to keen to sign up and bug him.
Also ive continued this ans another question in a post related to my vehicle HERE.
thanks

He has completed quite a bit on the transmission/transfer case. I just googled his user name and found him on another board, then used his profile info to find an e-mail address. As I said earlier, he shared a few pictures of his set up. He said he doesn't post online much and I can see why based on how he was received in the second link. I encouraged him to share his progress (other places) as this is a unique project.

I've also contacted xr4x4ti (the first link). It looks like his setup would be the easiest/most affordable to replicate. Still waiting on his response.

I would appreciate if anyone out there has the blueprints for adapting the t56 to AWD transfer case...or any transfer case (would actually PREFER a transfer case with H-N-L selection

odd application but I'm putting in a cj7. Plenty of room so open to all suggestions

When I first built the Quadra Deuce it used a Borg Warner transfer case out of a Typhoon and a 6 speed out of a F-body.

The out put shaft on the trans mates to the input of the T-56 no problem there. The adapter / extension housing on the tail of the trans was off an aftermarket Mustang conversion tail housing extension with a 1 1/2" chunk of 6061-T6 aluminum welded to it. I had to use the Mustang tail housing to move the shifter forward to clear the adaptor. Once the billet aluminum was welded to the tail housing extension we machined it to match up the to transfer case. But we clocked to 10 degrees up to get more ground clearance.

A note of caution. The Borg Warner engineers that I talked with claimed that the parts could only handle 500 hp in a vehicle that weighed no more the 2800 lbs. So the QD made 500 hp and weighed 2600 lbs. We never fail any parts in the drive train. It went 0-60 in 3.2 seconds as tested by Car and Driver on BFG radials.

I have the blue prints and drawings if some one really wanted to do it again. But there are better parts available now that will handle more power so unless you are building a light car I would go another way.

I know this is bringing a post back from the dead, but here is a completed car using a Trailblazer SS front frame section complete with running gear. It looks a little nose heavy to say the least.
