Should I modify my 750dp, or just go bigger?

I have my Holley 750 double pumper (4779) all apart for a rebuild (I got it used), and I just had a few questions. I have rebuilt a ton of carbs, so no issues on the "how to" in that respect.

I was just curious to see if there was any worthwhile way to increase the airflow on the 750 to make it a better match for my 422 sb. Or, would it just be easier to look for an 850dp or even a 950hp? 10.8:1, W2 2.08/1.6, [email protected] Lunati solid flat, 3.73 gears, auto w/appropriate stall.

I am kind of thinking whatever I do, it will just be a crutch and I need a bigger carb.
