The 950 is a misnomer, its a 750 with an 850 baseplate and isnt a very big carb for what you have.

The 950 is a good carb, but it is smaller and will lose top end charge, but gain you nothing down low over a modern 850 or 1000 HP.
I looked it up, and you're right, the 950HP carb has similar venturi diameter of standard 750, but throttle plates of an 850. As the 950HP carb has a recountoured/reshaped top entry for better flow compared to a standard 750, I'd think it would therefore flow more, but bby how much I don;t know. Obviously, Holley thinks that the carb should be rated at 950. Does removing the choke tower/reshaping the entry zone improve airflow that much? How much restriction is in the venturi diameter or base plate throttle bores/plates?

Interesting.
