For what it's worth, about 37 years ago, I had a red '65 Impala SS convertible, 327 with a 4 speed. It had a WCFB. I saw that it was a bit larger than the 265-283 carbs of the late fifties. That's probably both the last application of that carb, since '66 Chevy 327's had a Q jet or an AFB or a Holley, and the largest CFM rating. If that's what you need, you might try looking for one off of a 348.
