if you want to keep it simple for now, an adapter and carb from most similar displacement engine carburetors will work fine.
.
the advantage of the 32/36 and Holley knock'off 5200 series 2bl's is that they are
progressive linkage carbs. basically the '32' 'primary' side is smaller than original 1Bbl offering greater throttle response and economy at low flow rates -THEN with increased throttle, the 'secondary' (36) barrel contributes needed fuel and air flow for higher RPM flow rates. Opening secondary can give a 'kick in pants' feel to pedal like 4Bbl WOT..
.
universal and inexpensive Holley '2300 series' 4412 500CFM and 7448 350CFM 2 bbl's can even work but the large venturi's and small six flow rates can cause poor response and horrible fuel consumption. Apply caution in attempting use of any large CFM
over-optomistic carbs for small six use.
.
balance between keeping intake vacuum and carb working for performance and/or economy is a key part of fuel and the ignition timing equation.
