I was discussing the CFM ratings with my gearhead neighbor this evening and he had discovered the Motorcraft 2100 CFM ratings on several of his websites and he shared this with me. Many of you may know this but, carb builder that I am, I didn't know

. The number is stamped on the drivers side carb bowl...and in a circle. I hope I'm not appearing totally dumb here and again, I should have known this.....
