i have spoken with some people at Holley and they changed several things on those blowers, particulary the castings for the manifolds. Not sure about the snout though. I'm running really low boost but i'm not sure if that makes a difference either. I wonder what kind of stress would break it? pulley size or other?
The snout on your blower looks totaly different then the old one peice "street" deals. Those were the weak ones. Those one peice deals also took pulleys with the larger center hole. It was 2 1/8" if I remember right.
