Howdy Curtis and All:
My apology too Curtis. I just couldn't resist.
To be exact the Autolite 1100 used on 200 engines from 1964 to 1967 were rated at 185 CFM (Cubic Feet per Minute). Califorina Emissions 200 in '66 & '67 are rated at 156 CFM.
This is not the carb for supercharger or turbo-charger applications. You will want a carb that is more easily tuned, more durable, and had a better power enrichment circuitry. For these reasons and more, I'd suggest that you look into the Holley #4412, two barrel rated at 500 CFM.
Adios, David
