Sizing carburetor

Bewy said
The 650 AVS2 would be the best carb for your combination. Forget about the brawler, crawler BS carbs. Some just don't get it.....

I posted the page below on another thread on this forum. It is very informative about carb size. 383 Dodge v 428 Ford. Dodge was 3.3% lighter but was down 45 cubes, or 11.7%. Both had 3.5 axles & both ran 14.04 for the quarter. The Dodge was 1 mph slower at 99 mph. The Dodge had the 625 Carter AVS, Ford had a 700+ cfm Holley [ pretty sure 735 cfm ].
What this tells you is that the 383 with the smaller carb accelerated quicker but lost out at the top end. Because the trap speeds were so close, it indicates the 428 was slower for most of the quarter & only picked up at the top end. I would rather have a car that is quicker from 0-90 with a small carb......than 90 -120 with a big carb. And this is what many do not seem to get....

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: Moparts on the Web - Main Index
