Hmm weird AMS BSE is junk now??
What a joke! I got over 10,000 miles of 38psi DAILY and 9-9200RPM DAILY use on my AMS engine on E85. Everything seems great to me, engine still runs flawlessly!! Had the head off to put L19s in it at about 8K and everything looked great when we inspected it.

I don't think anybody is saying the machined down B-shaft is junk.
Both sides of the debate have good points.
LOTS of B-shaft bearings seize. It happens. That is the argument for the stub shaft.
If you incorrectly do the T-belt tensioner, you can create a lot of problems on a stock motor, but it's an even bigger issue on the stub shaft. Also, a bearing should ideally never be loaded as to produce a moment on the bearing, and using the stub shaft does just that.
