What carbs you pick would generally be a function of your (or your tuner's) "comfort zone" with a specific carburetor.
Choices would include in alphabetic order:
Carter W-1, WA-1, and YF. Stay away from the BB and BBR series.
Holley 1904, 1908, and 1920 series.
Rochester B's and monojets
Stromberg B series
Zenith 28 and 228 series.
(MOO) Ranked in terms of overall quality and performance:
(1) Stromberg and Zenith
(2) Carter
(3) Holley
(4) Rochester
(MOO) Ranked in terms of "user friendliness" (availability, performance/cost, ease of tuning, etc.)
(1) Carter
(2) Stromberg and Zenith
(3) Holley
(4) Rochester
Two Carter W-1's work exceptionally well on a stock to mildly modified 235.
(MOO = my opinion only, others may have differing opinions).
