I have a number of Holley 4150 style carburetors ranging from an OG 650dp to a Quick Fuel 1050's in annular and downleg.
Both of my 511" low decks ran best with a 1050. The annular drove better at low speeds (<1800 rpm) IMO. Both 1050 carbs needed emulsion bleed changes, IFR relocation, transfer slot restrictors, PVCR calibration, and at minimum a an idle air bleed.
I have an ADP 950 to try one of these days. It is OOTB.
