Yep. Either a converted small block Chevy distributor, or my favorite, an old Mallory dual point.

You have to understand that the 8BA series of engines used a unique vacuum only advance system where the carburetor and distributor were designed to work together as a unit. Some have claimed to have had success using the stock system with the vacuum line from the distributor plugged into one (or maybe both) of stock carburetors. It is still not an ideal situation, as the amount of vacuum required is relatively slight and increasing the number of carbs throws everything out of wack.
