A spread bore carburetor is any carburetor whose secondary barrels are larger than the primary. Period. That's the definition and the smaller Edelbrocks meet it. Just because you don't like it or agree with it doesn't make you right.
It does make them a spread bore, square flange carburetor. I don't really give a flip if it's splittin hairs. It's either right or wrong. you are wrong here. Thank you drive through.
Make another thread if you want to argue this. I don't want to get this sidetracked as usual.
