Hey all.
Pretty new here. Bought a 65 A code convertible for "the wife". Getting familiar with it.
Trying to identify the carb so I can either rebuild, repair or replace.
No tag, but the number stamped on the front lower left is C8VF J. From what I could see locate its a 1968.. but the V and the J I don't see any where.
It doesn't run terrible.. just leaks a little around the shaft on the top which I assume is the accelerator pump rod. Its also a bit rich.. The auto choke is opening completely when warm. I have adjusted the choke so its off all the time and it still runs a bit fat.
Questions:
Is it a 4100?
Is this an acceptable carb to run or should I get a 1965 4100? Car is pretty original
Am I better off going to something like the Edelbrock 1403 or the SUM-M08600VS

Any help or suggestions would be great.
Thank You

4300 off a 68, Might have been a replacement carb so that is why you can`t find an application. Looks like the intake says D1 on it so at this point intake and carb not original to car so maybe not engine as a whole as well.

That's not a 4100. That is a 4300. I think it was available starting in 1967 and used on the A code engines.

The 4300 was a replacement for the excellent 4100 4V carb. It was supposed to be more 'emissions friendly', but only excelled at three things: bogs, stumbles, and catching fire.

They were not a good design, nor was the later 4300D spreadbore used later. It is commonly referred to as a "pepperpot" for its propensity to burn. I would not recommend you use it, if you intend to actually drive your car - and since it is not original to your vehicle anyway, 'concours' doesn't apply here. Sell it to someone that needs it for their showcar, and get something better, like a Summit M2008VS!

Thanks for the reply's.
Again I am new to Mustangs. But not mechanics have been working of Cars / Bikes for 40 years.
I have a Chevy 3100 5 window - a 55 Belair and a lot of motorcycles in my barn.
If the 4300 is not the greatest option. Is there a replacement that would be best for me?
Seen there is an EB 1403 - Holly 4010 - Sum M08600vs.
My wife is just going to drive it on nice days as were in Michigan and its a convertible.
We are never selling it and just want it to be a nice cruiser.

Car has had a complete restoration prior to us. Appears to be in really nice condition.
Tons of new stuff. Factory Air - PS - PB - Pony Interior.
Is there a way I can identify the motor and intake easily? It has a C4 transmission.
Here's a couple pictures for reference.

You will have to look at the casting numbers on the block--near starter-- and any others you can find.

Nice car!

Not really sure why they would of used that carb, must have already had it I guess

I'd try and source an original 1.08 4V, none better in my opinion!

 

[Klutch]

The 4100 would have been the factory 4V carburetor. It's a great carb, but they are getting downright hard to find in good condition. When you do find a 4100 in good shape, it's pretty expensive.

I would recommend a 500 CFM Edelbrock or Summit carburetor. They are inexpensive and they work really well on a street car.

 

[RILUSI]

Ok.. I was assuming/hoping the motor & trans were original. (NOT)
Bought it from a classic car dealer that said it was "period correct".
What I do know NOW after this post is that the intake manifold is stamped D1JE - 9425-AA and the carb is stamped C8VF J. So the intake is a 1971 --- the carb is a 1968 4300 Autolite.
I'm at work and could not see any numbers by the head. The air unit is in the way and I have no flashlight and a dress shirt on.
Does the 1971 intake manifold cause any issues pertaining to what carb I buy. I assume the ones to replace the 4100 are square bore?
Thanks you guys for your patience.. I'm learning as I go.

Just spend some time reading old posts about the subject--lots to see including sample pictures.

Ford stopped making a 4 barrel intake for the 289/302 after the 68 Model Year, the D1JE-9425-AA intake manifold was cast for the boating industry, I recall Mercruiser using Ford Engines back in the day. I used the same intake manifold on a 71 Ranchero I bought in 1993. It is the same fit and function as the earlier intakes, just a different casting number. The 1968 carb is not correct for a 65, but may be desired by a person with a 68. I would not throw it away, but I would recommend trying to find a proper 4100 carb with 1.08 cast on the side of the housing, not a 1.12 as it would be correct. If you cannot locate one, a Holley 465 (1848) or Edelbrock 500 cfm will bolt onto your intake and provide good performance.

In addition, if you want to determine whether you have a 289 or later 302 in the car. Take a picture of pad between the bellhousing and rear of the intake manifold. A 289 will have a shallow valley, a 302 will have a flat pad with a partial VIN stamped on it. The 302 came on the scene in 1968 and they started putting partial VINs on the motor, prior to 1968 only HIPO 289 had VIN stampings.

C8VF-J was used on the 460 engine in the '68 and '69 Lincoln Continentals. This model would be a 600cm 4300A. The carb kit is a Standard Hytest 433B. These carbs are known to be temperamental and were known for hard hot starts, flooding and other issues.

The 4100 is a far simpler and more user friendly carb.

 

[Mustangerbob1]

C6Vf-J is a Lincoln 460,

The acceleration curve of a dying sloth.

WAY to big, and jetted to move a land battleship at don't spill my champagne speed.

 

[Grimbrand]

This is the carb I would recommend. It's a descendant of the Autolite 4100, and has annular boosters, along with some features that make it exceptionally easy to tune.

If you actually have dished pistons instead of flattops with valve reliefs, I would get the 500 CFM version for sure. It will run harder all the way to redline, and have better throttle response.

Here’s the picture of the back of the engine. I do not see any numbers back there. A little unsure about your description.
flat pad or valley. Hopefully you can tell by the pictures.
Thanks.

 

[kb65]

either the 500 CFM summit carb mentioned or a 500 CFM Edlebrock AVS-2

That triangular pad is the unused location for the early PCV system. You have no VIN pad, so your engine block is 1967 or earlier.

Your carburetor is for a 68 Lincoln 429, so unless it has been drastically retuned, is not suitable for your smallblock. You should find a 1.08 4100 Autolite™ carb, or failing that, a 500 cfm Summit carb.

 

[RILUSI]

Thanks for all the information. I know way more that I did just 48 hours ago.
So I have a 289 with the incorrect manifold and carb on it.
Is there any way to further identify the engine with out tearing it apart?
Thinking I might buy a new carb initially and keep a look out for a 4100 and eventually the correct manifold.
Is one of the suggested carbs better or about the same between the suggested SUMMIT or the Edelbrock?
Both come in 500CFM. Is that what I should run over 600CFM for my set up.
Thanks again

 

[65AScoupe]

If you want new Summit 500 cfm, however Autolite would be first choice!

Edelbrock is old Carters! No thanx!
