My thinking is that if the OEM was concerned about the big gap the most obvious place to change it is to change the shape of the motor housing so it fits. Raising the other end to close the gap results in the intake end not aligning so well with the hole in the main housing and perhaps interfering with the plenum. I hate to criticize when I don't know all the considerations that went into the design, but the motor housing is a new part which, presumably, allows for an engineering drawing, 3-D modeling, etc. They could have designed whatever was needed. Instead we have what appears to be a reworked DC-3300 motor housing. That approach constrains the design, as you are pretty much limited to removing the unwanted features. Which is exactly what the 'new' motor housing looks like. I hope there were non-obvious reasons for this choice.

Mine is currently working fine too, and airflow is significantly increased. When I got it back from Shopsmith I chose to use their new seals rather than improving because I wanted to see if they worked. They do, but I expect a much more limited life than in the DC-3300 due to the larger gap. I have plenty of time to decide which improvement to implement. I want to improve motor cooling so I'll probably do more than just seal it better. A word of advice. The other day I sucked up a couple of leaves while picking sawdust up off the floor, and they immediately clogged the system. In Dusty's earlier post: viewtopic.php?p=287388#p287388 you see there is an inlet grate that was not present in the 3300. It is effective at stopping large objects from reaching the impeller, a good inspection point for loss of flow. Easiest access is removal of the plenum.
