Carb on an Eaton blower?

Hi all...Has anybody dropped a carb "On top" of an Eaton blower?
I know the configuration is not easily suitable & would look funky but I am concerned that the Eaton cannot suck an Air/Fuel mixture thru (Seal breakdown?) I like the low profile of the Eaton & the low cost (Read, high production volume) Add to it the 'common' rib belt drive.....
Yes I would have to cut up the housing to add a "blowout?" valve or panel to avoid "accidental" forced removal of said blower.
What do you think?..........

What version Eaton? I'm not familiar with the M45/62, but the M90 and M112 might not work exactly how you want. On the M90 (Ford unit anyway) the square opening on the top (or bottom depending on how you look at it) is the outlet. The inlet is on the rear of the case. So to run a carb before the SC you'd have to make up some kind of intake manifold that mounted the carb and then mated up to the inlet on the supercharger. Sounds like more work than it's worth. I suppose you could run the supercharger before the carb and make it a blow through setup, but at that point you'd probably be better off with one of the centrifugal kits.

OK...perhaps I haven't researched all the available blowers...... I'm rather intent on the Roots type as I have a very tight engine parameters to work with especially toward the front, thats why I like the plain ribbed drive setup ...I can't have anymore 'intrusion' onto the front of the motor (4.3 GM V6), but I can go "up".
I was hoping to go typical Carb top outlet bottom arrangement with some or a bunch of fabrication....I have resigned? myself to fabbing an intake to suit my particular application...& I have found some forged blower low comp pistons to use for the 4.3.
