How strong is a super T-10?

I see them with two cases too, aluminum and iron, is one stronger? will a Super T-10 live behind my street 489? is it as strong as an M22 like I saw somone claim?

Re: How strong is a super T-10?

From what I understand an iron case (stronger) with the 9310 gears are comparable to an M22. But a run of the mill OEM Super T-10 with an aluminum case will not take the abuse an M22 would all things being equal. Sure you take a brand new Super T and compare it to an M22 that's been abused for thirty years the Super T might last longer. But if you take two brand new transmissions the Super T will not hang with the M22 for very long behind a big block with a lot of torque and sticky tires.

Re: How strong is a super T-10?

I would have to disagree with you about the M-22 being stronger. I think if your gonna run street tires and NO slicks you'll be fine with either one. What rear gear are you gonna run?

If that is the case then why didn't they put the 1st design Super T behind the LS5/LS6 Chevelles, L88 Vettes, and cars of that nature? Why was it the Super T-10's weren't put into GM cars until the power levels had dropped off so severely? I like Super T's, they are good transmissions. I ran a couple in my '71 for a while. But to say a Super T is stronger than a Muncie is laughable at best. I'm sorry, but when you are dealing with OEM stuff it just isn't so. I've heard of/seen several Super T's absolutely blow apart when they were being beat on. I've yet to see a Muncie do that. Sure they break, but I've yet to see one scatter it's guts like I've seen Super T's do.

Re: How strong is a super T-10?

An iron case/9310 ST-10 has a major performance advantage over the M-22:

Available wide-ratio gearsets w/decent first gear ratios!

So is a Toploader. That's why I want to eventually put a Toploader in my Chevelle. But weren't talking about Mopar and Ford transmissions here.

That may be true, but the severity of the close ratio Muncies 2.20 first gear is really over blown. Unless you are a drag racer a healthy big block with 3.31's out back will work just fine on the street with a 2.20. Anything above that is just icing on the cake.

I would think that the iron case super t-10 would be an improvement over the non here is specs on the super t-10 http://www.richmondgear.com/07pdfs/RG25.pdf

and also they have a new release of an m22z
http://www.autogear.net/whatsnew.php

AUTO GEAR COMPANY, INC. of Syracuse, New York is pleased to announce their latest alternative gearset for General Motor's iconic Muncie four-speed. The 'M22Z' (ratios 2.984/2.043/1.468/1.000) was designed to provide 'cruisers' an alternative to expensive overdrives. According to the company's Chief Engineer, George Sollish, "Now Muncie drivers can have the highway rpms of a fast axle without changing their gearbox. In addition, when paired with a 3.08 axle the M22Z gearset provides the same 1/2 punch of our successful M22W/3.54 combo, so there's no embarassment leaving a light, either. And like all our gearsets, the M22Z can be used in original equipment cases. We're also looking at older Jeeps -- they've used Muncies for years but have never had the 2.98 low we offer before now."

I would sure like to know more about the top loader conversion and the A833 converion

A833 is the Mopar 4-speed from the 60s-70s, pretty stout cast iron case transmission.

Re: How strong is a super T-10?

I ran S-T10's for years in my chevelle with a 440, centerforce dual friction, 456 gear, and sticky tires. I broke a few. The weak point for me was where the main shaft and the first gear come together. The needle bearings would mess up resulting in a new input shaft and first gear. These parts are getting hard to find. Just for cruising with treaded street tires one could live a long time.

The funny thing about M22's is I've driven cars with three different Rock Crushers. They all sound just a little different. But they all three sound equally as sweet.
