There's a guy with a 250 and 2 450 holleys on it. This set up seems real odd to me especially the side float carbs and that small cfm. Shouldn't one run center floats on these? 4150's?

Gary, how lean were some of the cyliders compared to the others?

Center ones were very rich, especially at idle (black plugs). Lots of loading up, rpm oscillations, even with MSD.
CMC around here sets their 502/250 blower motors with twin carbs, and they have a very nice idle.

What carb were they running? What CFM do they run with dual setup?

They were running Demons, 650s I think.
Try the holley wesite, they have a lot of good info, even on marine supercharger setups.
They have a tech line too. Never tried it, but it may help
