Found this in my shed yesterday....

That's very cool stuff, Brooks. Thanks for sharing. I'm confused on one point though. What time frame are you saying this carburetor is from? I ask because the early factory style AFB carburetors were smaller than the 5 1/8" diameter where the air cleaner installs and that one appears to be 5 1/8" which indicates it is a later Competition style, like you do say. I bet it would be very responsive on a slant 6.
