Oldskool dual 4 carb setup

[JIMnWV]

Slowly getting around to actually starting my 55 2nd series project, decided to use this dual 4 setup I saved from a 72 Chevelle I once had. Been looking for carb kits for them and have narrowed some down, but I have yet to find any info as to what the CFM is of these carbs. Only info I find for the Carter # 3705s is that they are factory 426 hemi dual 4 carbs from 1964-65. Anyone have an idea as to the CFM of these carbs?? I always worked with Holley and Quadrajet carbs but not Carter. Any thoughts are appreciated.

Yes, those are part / model numbers for them. number is on the triangular metal tag attached to top rear corner screw. I did after a while find that same 750cfm info. Seems alot of air for a sbc but the motor that system was on in my o'l 72 chevelle sounded very good. Thats why I pulled this setup and replaced with a single 4 system when I got shed of the chevelle. Seen a 3 deuce setup that sure looked good too, I like unusual things that are not seen everyday.
