273 4bbl setup

I appreciate all the replies and validation of the numbers I have.
To start, my 65 dart is all original.
I have tracked down a 2465726 intake manifold, thank you Frank.
I work at O'Reilly, I can source parts. I found a 3615S through a Tomco pt # 4-99. I got 3 different numbers including a 4122, a 3615, and a 4612. I went with the 3615, it has the same secondary configuration, choke as the 3854. Slight increase on cfm and fuel will be of course compensated when i have the heads reworked as well as the dual exhaust.
So I need a 4bbl choke 65 to 67 year models, and thank you for coming up with and verifying numbers I have found. I actually came across a online a Carter manual that pinged the 170ba-817s oe carter number, as well as a plethora of carb specs for marine and industrial use Chrysler, and a couple GM's motors.
As of right now, I have a stock 2bbl. I am installing a 65 manifold with a higher cfm carb but I need a stock choke. I have checked the butterflies for interference, the older big block carbs weren't quite as big as the later ones, there are no true cfm specs on these but most advertised in the muscle car era were 650-700, these being slightly smaller, early 60s was a coming of age for performance cars and engines designed for performance, not just running well. I'm only looking to increase hp to the 200-220 hp range with stock setup converted to a 4bbl stock, heads cleaned milled stacked and packed, and dual exhaust.

At this time, I need an air cleaner, a choke, and a week to tear it apart and put it back together.

I do have a set of finned mopar valve covers.
