360 carb question - Carter c-6090

Sorry, that chart is as relevant today as the day it was published. It is chart version of the graphical version published in the original Mike Urich Holley book. What the chart doesn't say [ maybe it just wasn't quoted above ] is that the numbers are based on 100% VE.

Sorry, I'm not going to run a 500 cfm carb on my 273. I've run a 750 cfm TQ on it and not even close to the same.
