I can’t see that tri power adapter doing anything other than causing fuel puddling issues before it gets to the intake. Single Holley setup all day long. If you really want something different that will out perform either setup, find yourself a Holley 3 barrel or a Holley list number 6710 DP ThermoQuad replacement. A similar 6213 (or one of the several list numbers according to which make they were designed for) 800 cfm DP Q-Jet replacements.
I have some already rebuilt thermoquads. right now I am experimenting. For track use or street racing It will be the Holley. For cross country cruising the thermoquad, tripower for car shows. I want to be able to change the setups in 15 or 20 min
