OK aqll you Holley experts.

I have 2 matched Holley double pumper carbs from Davinci performance.

There are no choke horns. So I do not have the regular numbers.
on the body is the following number: 6R 3767 B

One metering plate has this#: 11182

and the other metering plate has 11398

I am trying fugure out what CFM they are.

I called Davinci and left a message but they have not returned my call yet.

I guess they are too busy building carbs for Orange County Choppers :biggrin.:

***************************

I also have a third Holley double pumper carb I am trying to identify.
It has 3442 on the horn and 6R 5533 B on the body. There is anothe number on the horn above the 3442 that ends in 4 but can't make out the rest.
