It's probably an Auto Gear Equipment with Italian gear set. Available in close or wide ratio, I believe.
If you want to shop around, I believe Paul (http://www.5speeds.com/index.html) is a member, and Gear Rhonda is both knowledgeable and entertaining.
There's also T&B (www.tbtrans.com), and Standard Transmission and Gear (http://www.standardtransmission.com/mainbody.html, among others...

There is someone here that put over 1000HP through the a TKO 600 many times over on a chassis dyno. 650HP is a very conservative rating for the TKO 600 and it could even be that it was tested over an extended period of time and they came up with that number. Short bursts as in racing the tranny will hold a boat load more power than 650HP. 
I would question how he gets 850HP rating out of a Muncie tranny which was rated stock at less than 400ft/lbs probably closer to 300ft/lbs

The Supers I'm familiar with are based on the Muncie's architecture, but built with much heavier duty components, including the case and mid-plate along with improved M22 type gears. I like the idea, but do question the value vs. the TKO, what with an extra gear...

(Try that with a TKO) Has run it 4 years now with no issues. They are bulletproof and a direct bolt in. The components are available through Autogear.

They are based on a Muncie M22. But the Supercase is a much stronger alloy, thick reinforcing webs everywhere, Thicker mounting ears, Iron midplate, better gear material, rollerized 1st gear, roller side cover, stronger mainshaft, and beefed up intenals throughout. I have one for my 63 built by Powertrain Performance. He has a 57 Chevy running a 540 with 3 stages of nitrous and a Ford 9" with slicks putting out well over 1100 HP and runs deep into the 8's with one of these. 5000 RPM launches and brutal powershifts. (Try that with a TKO) Has run it 4 years now with no issues. They are bulletproof and a direct bolt in. The components are available through Autogear.

Who said that
Does this quote look like I said up to 300ft/bs"I would question how he gets 850HP rating out of a Muncie tranny which was rated stock at less than 400ft/lbs probably closer to 300ft/lbs"
Now that you are calling BS I will call you out to provide the factory torque specs on the M22 otherwise you know what to do
To another poster. Where is your evidience a TKO 600 won't handle a 5000RPM launch from a 1100 HP motor, allot of assumptions going on here and there is even more
Also you can cruise at 80mph @ 2000RPM with a TKO, try that with a Muncie

Short term, I'm going to rebuild my Muncie w/good parts and install that HD mid-plate. Beyond that, I'm looking to a future with a 5 or 6 speed OD transmission, whether its the TKO 600 (more likely) or a T56. As much as I like the Super Muncies, I just can't make a case to myself justifying that kind of expense for another 4 speed, and I'm not about to change my 3.55:1 (12-bolt IRS) out for a "mileage" gear. FWIW, that's my situation...

IMO any trans that you should buy, should make your motor run in its optimal powerband. So you have to take into account your rear axle to. If you stay below your powerband your engine will not be happy.

Not meaning to highjack here but Skunkworks, I thought the 12 bolt conversion only worked with 3.70's and shorter gears. At least that's what it says on Tom's site.

I'll sell you a Auto Gear Super Case, Antonio Masero Italian gear set, close ratio M-22 for $1250 (shipped to any of the 48 states.) I don't need it as a spare anymore for a race car. Muncie is early 27 spline (TH 350 spicer 1310 U-joint) output shaft with all new parts. I think Jet Boat Bill wants over $1600 for the same transmission.

I had my M22 rebuilt localy with beefed up internals. Nothing crazy. Cost me $200. Its handling my 600hp nicely but I'm not dropping shifts above 2.5k and its not a track car.I will go to a 5/6 spd in the future. I was looking up Dodge Viper 6 spd transmissions on ebay before I got to this forum. You can pick one up from a wrecked viper for $300-$500 and a fully rebuilt one to handle well over 1000hp for $2k. I think a supporting forum company even makes some adapters for the viper 6spd to our cars by way of a bellhousing adapter plate and shifter consol adapter.
I'm leaning towards this option when I change my trans over the next two years. I need to get more mpg on the highway. 4th gear is killing my wallet.
but its funnnnnnnnnnn

First
GM never published any ratings on any transmission.
I don't know where people get ratings from. I rehashed this many times before. Loading a tranny with 400 ft lbs against a 3.08 rear compared to a 4.88 rear works the gearbox differently. Ratings are a benchmark that can go either higher or lower depending on a bunch of variables.
Second
Lots of people selling "Super M22's" Some don't comply what the orignal design was speced out for.. So look on the Autogear site for Authorized Distributers. New M22's are around 1800 to 2000. Most of these guys are using Chinese M22 Gears with Autogear cases.
and Third
As much as ratings for transmissions are cool bragging rights. The bottom line is that these new Muncies can get unstable above 700HP.
