ZZ, a 427 and a 434 are essentially the same engine displacement.
If Gary is running an 850 double pumper with annular discharge boosters and you are thinking the solution is to go smaller than where you are right now, Gary's message should hold volumes of information about the answer to your question re: going down in carburetor size.
Your challenge is not carburetor size. It is learning how to tune and use the equipment you already have.
