I agree, many are reaching or have already exceeded the limits of this OEM stuff. There was another thread asking about aftermarket 904 cases. You can put $50,000 worth of parts in a stock case and you still have that weak link. Finding decent cores is another issue. I'd like to see someone step up with good cases for Chrysler transmissions too. But the development of the T400 based stuff is way ahead at this point. I believe that's the reason for a lot of these Hemi Super Stock guys going manual. Same problem with blocks for small block projects. Guys can make power, but they're trying to find blocks that won't break in half.

You just have to decide if you want to keep beating your head against the wall.
