But let's not get too far ahead of ourselves. I need to make sure I can get this blower functional before we go purchasing a carb for it.

Years ago, we were able to get Holleys to work with Roots Blower. This was long before there were "blower" carbs. It is still pull thru as with a NA motor. But I've heard that Blower Carbs are easier to tune for roots. Haven't used one.
The last Roots steet car I built 1990 had a BM and I used a 750 Double pumper and it ran great, no over richness when I tuned the carb.
