Does anyone know the cfm of this carb? It is on my '76 460.
I know it isn't the 4300, which was rated at 605 cfm...
It is not the greatest carb in the world, for sure, but when I upgrade, I would just like to know where I started from, ya know?

I think most were in the 600 cfm range. My `85 had a factory 600 cfm Holley. Upon replacement I used an Edelbrock 600 assuming Ford knew how much air these motors needed.

It seems as though many people go bigger, with a 750, when they replace, but that would only be helpful if the motor was going to be running in a higher rpm range.

Good luck,
