352 Carburetor Replacement
I got the bad news that my 2bbl carburetor needs replacing. So I'm looking at some of the Holley ones.
2bbl: Holley Model 2300

or
4bbl: Holley Model 4160

+
Edelbrock 2105 - Edelbrock Performer Intake Manifolds - Overview - SummitRacing.com
I was reading this and would I really get an almost 50% boost of Horsepower?
FE/FT 352 and 360 Big Block V-8 Ford Engines .: Articles
And my last question is, how much would a 4bbl affect my Gas Mileage?
I currently get around 8mpg in my '67 F100 (with 3 speed column shift) while running the choke on all the time since it can't seem to idle.
If you have any other carbs to recommend please do so.
Thanks!

First, you will not gain 50% in the HP department.
As poor as your current carb is, you will probably go back to whatever your truck had to begin with, minus the wear and tear losses.
Your current 2bbl--why can't it be rebuilt? If the shaft is too worn or it is cracked, fine, replace it.
Why not find another Ford 2bbl? Millions served, available reman'd and used.
The 2300 you link to is a 500 cfm carb. That will work, but you will probably have to change the accelerator pump, as they usually come with a 50cc job that is too much for a stock motor like your 352. (had one on my 289---really hauled axx after the bog and cloud of black smoke)
As for a 4bbl, you can get better mpg out of a 4bbl, but you probably won't. If you have a leaking, bad 2bbl, a nice tight, properly adjusted 4bbl will do better. Once you start opening the secondaries, your mpg will plummet. Although it would be hard to get worse than your 8 mpg.
So yea, you can spend almost $600 on this problem and you will get better mpg and performance.
Or you can spend $50 and get almost the same results.

We've already rebuilt the current Autolite 2100 that's in it.
We took it to a shop and that's what they said and it would be around $575 for a new 2bbl carb and installation, so I figured I could possibly get a 4bbl and a new intake manifold.
What's the performance gain with the 2bbl and the 4bbl?

$575--I hope he's kissing you while he's doing that.
If it's already rebuilt, what is wrong with it and why didn't he find that out BEFORE the rebuild?

Carburetor Lookup
Performance gains?
--the bigger 2 bbl will run about the same as your current one, maybe a little softer on the low end due to the bigger venturi. Once you hit 3500-4000 rpm, it will perform better and you will gain some HP. Until you float the valves. Peak HP on a 352 was what, 4400 rpm?
--the 4bbl will run about the same as your current one, maybe a bit better on the low end due to the smaller (maybe) primary throttles. Then, when you hit into the high 3000's, depending on load, the secondaries will open, and you will gain some power. Unknown what amount.
BUT, like I said earlier, nothing like the 50% you referenced in your first post. The engines there had different cams and higher compression to get to the higher HP numbers.
If he wants $575 to put on a "new" 2bbl, look for about $3000 for him to lift that boat anchor iron manifold off your motor and install the new one and 4bbl carb....

Well, we rebuilt the carb a few months back hoping we could fix it ourselves. We took it in because didn't have the tools to check everything.
Thanks for clarifying the performance gain between the 2bbl and 4bbl stock engines.
The $575 included the carb and installation.
I'm just trying to weigh out if it's worth it to spend $300 more for more performance.
This is my first truck and I hope to keep it a while so I might as well spend the money on new parts and prevent stuff like this from happening later.

$575--
It's a $50 used, $200 tops reman'd carb.
Installation takes less than 30 min. If he charges $100 per hour (high), that's $50 in labor.
I changed back and forth with my stocker and the Holley 500 two or three times in my driveway in a couple hours, which included "test drives". The major issue was gasket removal when changing carbs.
I just don't get where this is a $575 job.
The tools to check the carb are included in the rebuild kit. It is (was when I did it) a cardboard float level gauge.
What is your carb doing?

Wow, some prices there.
Just get one of these for the minimum bid. Then take off the 4 nuts, disconnect the fuel line, vacuum line and accelerator then simply replace. Could do one of these with my eyes blindfolded in 15 minutes.
I've dealt with this seller before.

I looked at that one, but I figured for $100 more why not get a brand new Holley?
Is there no difference between them?
Or is it just not justifiable for the extra money?

Nothing more reliable than an Autolite 2100 or 4100. I have 10-2100's and 4-4100's. Replaced the 600CFM Ford Performance Holley, from 1973 and a collectible, on my Cougar with a 4100. So much easier to tune and rebuild in the long run.
