Just wondering. I have heard some stuff about these cases. Are they better then the AS41? Is the alloy different, stronger? I need proffesional help.

If it's in good shape, it is a good case. The new AS41s are supposed to be better, but I'm still a little suspicious of that claim. I wish somebody would do an actual metals analysis on one. I always thought AS41 was an actual standard metal formulation, period. Anyway the AS-21 was designed for the hotter running fuel injected engines, so it is supposed to stand the heat better than the old AS41 at least.

What about the plumbing and such. Is it the same as a AS41. Are there any other special parts I would for the AS21 vs the AS41?

The original AS21 cases didn't have a fuel pump boss. You have to run an electric pump. The Brazilian ones had the fuel pump. Other than that it's pretty much the same.
