Thanks Gordon

I thought though the "Carb Size" paragraph of your Hagerty link interesting. In order to do the math in that paragraph I went on an internet chase:

To figure out what the cfm for my engine is, I found this: https://www.inchcalculator.com...tor-size-calculator/

Once I had the engines total cfm, it needed to be divided in half (half for one carb, half for the other carb).

Then to see what carb is a likely fit, I compared my cfm per carb to the list found on this link: https://shoptalkforums.com/viewtopic.php?t=128512

In the end, I became confused. There is either a lot more to the engine cfm/carb size formula, or many of us are way over-carbureted. I suspect the latter to be more likely. Which makes me wonder how many of us REALLY need dual Weber 44s, (or for that matter Dellorto 48s)?
