Super T-10
So I traded an old Honda chopper to a buddy for this transmission. I told him I had recently got a '74 Coupe(co-incidentally in another motorcycle trade). He said "funny thing, the trans came from a '74 'Vette". I thought they all had Muncies. Maybe big blocks had the Super T-10?

I used to own a 1974 454 convertible that was equipped with the ST-10... VIN was in the 31000 range.

My VIN is 1Z37J4S435160, maybe I already have the ST-10? I know one thing, the shifter is sloppy as Hell. When I start Hurst shopping, are the Muncie and B/W shifters interchangeable?

The Vin will be on the tranny on the right hand side on an extruded boss. Also the date will be on it as well somewhere-I can't remember where though, it's been so long. It'll be a 902,903, or the stronger 904 which has the steel mid-plate. They came in either cast or aluminum. How many rings around the input shaft?

This was the message he sent me, the trans is at home.
"here is the borg warner super t 10. it has the larger output shaft(th400 size) and it also has the vette only front driveshaft yoke. its numbers show it to be a 74 and made in the vette plant"
I haven't really looked at it, didn't know what to look for.

I did a google search and several pages for Pontiac Power came up, but they were all blank when I opened them. I am using google chrome.
I did see this article:
http://www.hotrod.com/how-to/transmi...-transmission/
The article stated the ST-10 is nearly as durable as the Muncie. Can of worms, anyone?

In my opinion the ST-10 is stronger than the Muncie to a degree. Though both are identical gear boxes except that the Muncie's have a 7 bolt side cover opposed to the T 10's 9 bolt. Both will except Hurst shifters for any application just that the ST-10's have a way broader gear ratio from 2:43-3:42 and a few interesting ones in between. I had all of them at one time lined up against a wall as I was collecting them for a project I was building at the time and I wanted to have options. I'm a firm believer of leaving the Muncie's to the restorer's of classic muscle cars. One thing though about the ST-10's is that a person isn't confined to low ratio gears in the diff just to make the vehicle launch. I had a '66 "B" Pontiac 468 BBC with an '81 6 groove ST-10 904 cast case with the steel mid-plate and I couldn't hurt that tranny no matter how hard I beat on it. 3 gears of rubber all day long...........

I'll have to go out in the garage tonight and look at the grooves on the ST10 and see if its a close or wide. I have 3.55 in the rear. Really though, If I ever pull the trans I'd be a fool not to go back with overdrive. Then I could get 3.73, or 4.11...

Super T10 Vs Muncie
In answering some questions. The Hurst Comp plus shifter and install kit has both rods and components for both the ST10 and Muncie. 69-79 vettes
The factory GM ST10's were issued in vehicles when power levels DROPPED. They were never issued in big block cars. The T10 was phased out by late 1963 ( May June) because levels were on the rise and the ST10 was in full production by 1975 when power dropped.
The advantages of the ST10 are lower ratios with the sacrifice of performance over economy. So the 2.88 1st gear and 3.42 first gears were typically coupled to 3.08 axles.( Ultra wide ratios ) Factory GM ST10 units are not as strong as the 9310 alloy PowerBrute units. GM issued ST10 transmissions are much weaker than Muncies if we were comparing apples to apples. We cannot because of years of age and abuse on used units.
About the new transmissions. The new AGE Muncies and new ratios offered are on a whole new level that a new ST10 will never achieve. The Richmond Gear version is still available and is now owned by Motive gear. All new Richmond ST10 units are 100 percent retooled with state of the art manufacturing in China and assembled in the USA.
Here are some useful links: The Original Borg Warner PowerBrute ST10 catalog ( rare )

The ST-10 was phased into Corvette production toward the end of the 1974 model year. They were most certainly installed behind 454 Corvettes built during the final months of 1974 production.
