Mark,
I did not see your question to Langdon but his answer seems to refer to one carb (no plural with "the 32/36"), whatever that is (probably a carb in your question to Langdon? ).
What is the total CFM for whatever Langdon is suggesting?
My experience with Langdon was not the best. He sold me what carbs he had in stock, and then he wondered why I bought what he had personally recommended. I also had to wait for other parts that he never told me that he did not have in stock (dual intake and exhaust manifolds). I ended up with a really nice/smooth/reliable 2-carb progressive 2-barrel (Carter-Webers) set-up that would be excellent on a 235 but they are not enough CFM for a 261. This Spring I'll be selling the whole set up and going with a 2-barrel Holley from a GMC 302 or a 1-barrel Zenith from a GMC 270.
