Carburetor Question
I need to replace the Carburetor in my '85 F250 (460). I'm a novice and am trying to identify the type of carburetor I currently have so I can figure out what I need to get as a replacement. I don't plan on using the truck for anything crazy... mainly as a work-horse (hauling gravel, dirt, wood, and my 15 ft boat).
Here is all the information I was able to read off of the current carburetor when I pulled it.
Mfd By Holley for Motorcraft
12R-9434 (near one of the mounting bolt holes)
E4HE 9A589 DA (found on the mounting plate)

No such thing as a dumb question, only those that go unasked. 4160 is a modern carb, that is designed for power and adjustability. Holley 4180 is OEM equip carb that is designed for emissions and economy. Working on dragging up articles for you now

How To Understand The Holley 4180 - Mustang Monthly
Holley 4180. If you have a good core you can pay pony carbs to rebuild it and its better than stock. It is like 300 or 400 bucks.

Yep!
Back to the carburetor.. I've been researching Holley 4160's, and am a bit overwhelmed. I've never messed with carburetors, so bare with me.
I'm assuming mine is electric choke - but I really don't know what I'm basing that assumption off of? Is there an easy way to differentiate? Also, are there different models of 4160 carbs for each size of engine? I notice a lot of the dealer sites list that they're used in 302's, as well as some other small blocks. Is this just a more popular application than for a big block 460, or do I need to locate a specific model for the 460?
I'm not a complete moron, I swear.

The 4180 runs off an electric choke, which if IIRC is 7.5v. Typical electrical chokes are 12v because they are the entire choke system. The 4180 utilizes a hot air assisted choke, passenger side (left) of the block, a thin tube from your intake to your carb. You also have a hot air riser which is the large tube going from your exhaust manifold into your air snorkel (if factory), and then lastly you have the factory 7.5v hot pill electrical choke (as modern carbs have).

Holley 4160 (P/N: 0-80457S)
Would this be a good match up for my application (85 F250 / Manual Transmission)?
Will the mounting plate from my 4180 work with the 4160? Or will I need to replace that as well? It appears I currently have a spread bore setup, so I'm guessing I'd need some sort of adapter?

I have the same 80457S carb, all I had to do was buy this to make the kickdown work:
Holley 20-60 - Holley Ford Transmission Kickdown Spring and Bracket Sets - Overview - SummitRacing.com
Since you have a manual you don't need anything except the carb. Get on the Autozone website and search all the stores in your area for the 80457s, my local store has them on the shelf for $199. I discovered that after spending nearly $300 on mine.

Glovemeister, it is a little rare now, but the carb I liked best on a 460 was the 1969 428 CJ 735cfm Holley. It actually will almost hook up to the factory fuel line on the 460 has the kickdown if needed and super throttle response. Ford PN C9AF-9510-U, Holley list-4609.
