Different folks will have different suggestions.
My favorites:
216
Carter W-1, Carter YF, Stromberg B, Zenith 28 types.
There are many different individual carbs of each type.
235
Stromberg B, Carter YF
Also good Carter W-2 and Zenith 28 or 228 universal
261
Stromberg B, Zenith (from a GMC 270), Carter YF (from that company whose name is the same as the last name of a country singer from Tennessee
)
Other possibilities (established companies) would be the Rochester B and the Holley 1904 (Personally, only recommend either of these on numbers-matching show vehicles which are not driven).
