Blower motor

Hey all. I have been replacing and upgrading as much stuff in the bird as I can. I have noticed that the blower motor doesn't blow that hard. Would replacing the motor help out? Are there any "upgrades" that I could use? It would be nice if I had to hold onto my hat when the motor is on high. I know that isn't possible, but a higher output than what I have would be great. Anyone changed there's out and noticed an improvement?
Thanks guys.

Have you compared its output to one on another F-body? If there is an actual difference you could simply have an obstruction. If it blows the same, probably nothing you can do within the realm of reasonable to increase its output.
