Holley Carb ID --Help Needed

[flynbuick]

I have a dual line Holley carb that must be 20 years or more old that I need to ID. I believe the number is:

3310-2

0124

As best I can tell it might be a 750 CFM but I cannot find the exact number in any reference.

You got a 750CFM Vaccum secondary carb there. Are they any good? Yes, there a good carb but a double pumper will make more power or at least thats what I have found. My car picked up about a 10th using the double pumper. Hope this helps :)

Would anyone like it for $75 plus shipping and packing?

I can post a pic.
