carb ID

I bought a bunch of stuff at an engine builder's auction yesterday. I can't seem to ID the Holley carb. casting #6R 4585B on the air horn. Base plate #11469. Metering block #7204 and #11075. electric choke, vacuum secondaries, single pumper. It will look nice next to my 45 cam shafts I bought. It seems large. Holley street avenger. Thanks for any help.

Holley says it's a 570 CFM.

Re: carb ID

A search of the net shows that no one seems to know a lot about that carb but a lot of people ask about them.

Is that the correct "list" number The number on the air horn that is behind list ______ ?

The number on the air horn is 87670 and under that is 1871. Holley seemed a little confused about it. It seems larger than a 570 CFM but I am no expert. It came from Gaerte Racing Engines/ Topp auction. Thanks.
