What the all-knowing Bewy does not "seem to get" is that a fifty plus year old magazine road test involving three cars from different manufacturers tells us very little (IMO) about optimum carb sizing. And that 383 Super Bee ? That's the fastest stock one I've ever seen road tested in a magazine. It makes me suspect that it's been tweaked/supertuned. The 428 CJs were typically faster than 383 SBs and RRs. Then there is that Carter vs Holley dyno test from fifty years ago that you referenced multiple times. It could simply be the result of the Holley having a secondary spring that was too stiff. Easily corrected. We know you hate Holleys. If you want to prove their inferiority, maybe you should post up more evidence than the same two sources. Here's a dyno test involving multiple carbs on a 383:
