what carb do I have?

[jmp]

How do you figure out the details about a given carb? All I know is that it is a 4 barrel Holley (says 'Holley', and has 4 barrels! ). But is there other identifying marks that I can use to figure out more about it?

(It's actually a spare carb, so I'm thinking about selling it.)

JMP,
If you will get the number off of the intake horn I will look it up in a Holley book I have tonight. Without that no will be able to help you out. Let me know if its spread bore or not. That will help as well.
