I don't recall exact numbers right now but most 205s are rated around or a bit above the 241 which is rated at around 1000 ft lb on some hocus pocus scale that New Venture used. It does not seem to correlate to engine torque directly. The 241HD is rated at 1400 and this is matched by one version of the 205 if I recall correctly. While the aluminum case doesn't inspire a lot of confidence, remember that the bearing retainers/end plates of the 205 are also aluminum.
For whatever reason, my 241HD is stock, original, unmodified and still holding up. I do change the ATF at least every 15,000 miles.
