Eddy vs Holley CFM ratings?

Well said 273.

I seen a video of a Holley tech set flow testing a carb. There all wernflow tested I beileve. I don't know about the Carters.

Now 318 willeun made a mention of "Better put a 500 on that 318."
That would depend on the engines useage and power output.

A TQ carb is a super flexable carb due to the spring loaded secondary side. Once it opens without an issue, your done. IF it opens fully, then the engine needs (or can use) it.

I wouldn't want to use a Holley 800 inplace of a TQ on a small engine of questionable power rating.
