Does anyone know what the CFM rating a 2150 2 barrel carb have? Did Ford make a larger 2 barrel other than the standard 2150?

 

 

There are probably half a dozen different cfm ratings for the 2100 series carbs. On the left side of the float bowl there is a number, ie- 1.08, that indicates the diameter of the venturies. I believe the 1.08 is somewhere around 300 cfm.

 

I read somewhere that two barrel carbs are measured at a higher vacuum than a four barrel. I don't remember whether it was my Holley or Rochester book. Check on the Holley website it may give the cfm rating for a carb and at what pressure drop it is rated.

 

Think the biggest were used on the short lived 429 2V. 1.33 425cfm ? The original post is 24 years old.
