If you aren't a hard core drag racer, that stock output shaft will do okay. When I say hardcore, I mean you have a car with suspension set on "kill" that dead hooks, and you need to dump the clutch at 4-5,000 rpms to keep the engine from bogging.
That's what usually kills it. I've twisted a couple of the smaller output shafts, never actually snapped one, but I've seen them snap like a twig though.
If you run a drag radial, have at least "some" tire spin, and you dump the clutch at 3,000 rpm or less, it will probably last you forever.

does anyone know if the tr6060 can be put into our cars?

You can go the T56 Magnum route,,,,which is a TR6060 that has a modified tail housing so you can use the torque arm.
They run in the $5,000 neighborhood.
It's a stronger transmission, with larger gears, better syncro assemblies, Beefier input shaft (even though they still maintain the same T56 26 fine spline tooth count), and they come with the viper style 30 spline output shaft.
Frankly though I don't care for the gear ratios much, they are spread further apart than the T56 in all gears,,,and it doesn't have as much overdrive. I don't care for the steep first gear ratio's either. I'd much rather spend the money to beef a T56.
Well here,,,you can compare for yourself.

T56's aren't bad trannies and I didn't mean to imply that. I just see things inside them that GM could have done better. When you rebuild many Muncies and Top Loaders and see how robust they are, then wonder why GM would resort to things like plastic parts ( like shift fork pads) instead of bronze inside these T56's it just makes me scratch my head. Probably had things in mind like noise and comfort instead of durability. Guess that's what sells cars nowadays.
Even some small upgrades in parts makes it a pretty good trans, but I'd still like to see a larger output shaft in them. I've twisted a couple of those puny 350 turbo sized shafts.

You might get harder accel in first gear but that's about it. From there the gear spread is further apart in every gear, so you will get more rpm drop on every shift and longer time for the engine to recover. That doesn't really excite me.
You can just put more rear gear in the car with a T56 and get all the hard acceleration you want But there is no fix for that gear spread in the 6060,,no matter what you run you still have that rpm drop at every shift.
