Intake and carb choice

I ran 2 more or less stock 750 edelbrocks on my old 440.all I did was set the idle and change the metering rod springs .my old 440 was set up like yours.for what I had in the engine I thought it ran pretty good. I ran a bunch of 11.70 in the 1/4 with it in my 3600 pound 65 Plymouth B-Body.wish I still had my old set I would of let you try them out.but if you wanted to stay with the holley I would get the 450 ones.
