Yep, i reckon that there's a Holley. 
If you look on the front of the air horn in your picture you should see some #s stamped - those are carb "list" #s, plug those into a search engine and it will bring up everything you could want to know - manuals, rebuild kits, etc.

OK...I looked at the numbers stamped on the air horn, here's what I saw,
8C457-8 2802, when I search it, I find 80457S, so I'm guessing I read the stamp wrong, anyway it comes up as 600CFM Electric Choke, doesn't give me the model number, so I have 2 ?'s, is it a good carb for my truck, ('79 F150-351M) and what is the model Carb

Looks like this is what you have, or at least a little older version. It is a good carb for your truck. That link will give you all the info you need, just read it up.
