Carb cfm

Barry, your comment about 950 and 1000 Holley carbs not being related to cfm is interesting. I'd guess that is probably true from the Holley engineer's perspective, but if you go to any parts reseller, like Summit for example, they say right in the literature that the carb is a 1000 cfm carb. Here is the carb I'm running, from Summit's web site:

Something tells me that the Holley marketing guys got involved before this carb was released LOL!

Based on my testing, and other comments I've read here, this is obviously not a 1000 cfm carb. But most people are going to assume that the advertising information is correct, and that they are purchasing a 1000 cfm carb. Just goes to show that there's more to this stuff than meets the eye, and there is no substitute for actual test results.
