When looking for rebuildable cores for either a WCFB or a 4 jet, keep in mind there are different sizes of both. The 265 and 283 up to at least 1961 used a smaller carb than the 64-66 283. The 250 horse 348 used a bigger 4 jet, that was carried over to the 62-65 327 250 horse,and the 64-66 283 as well. A local racer was looking for a WCFB for a '55 he was starting to build,and I had one from a 65 327 that I once owned, (the only part I still have from that car),and it was considerably larger than the 265 unit. The 63-65 340 horse 409 used a large 4 jet,but it differed externally enough to be very obvious. Just be sure you get the right unit. If you plan on racing a 65 327, let's say, and inadvertently got a '60-61 283 carb on it, that could be the reason it's not real fast.
