1964 1/2 4 bbl Carb replacement
« on: January 21, 2010, 01:01:41 PM »
I have a 1964 1/2 mustang 289 with a 4 bbl FoMoCo carb # C4GF.  I am having trouble with it and want to replace it with a new Carb.  I see a lot of them available with electric chokes, and manual chokes, but nothing that is a bolt on replacement.  What is the easiest and best replacement.

I appreciate all the advice you can give

I second the motion.  You can't find that Fomoco carb anywhere.  And I doubt a Motorcraft 4100 would fit on that 260 intake.  Are you positive you have a 64 1/2 289?  Ford didn't start putting in 289's until after August 1 of 1964.  Check your build date, and see if you have a generator instead of an alternator.  If it was built before August, and you are certain that is the original engine, then it is a 260. 

Here is a decoder to decode your VIN.

Quite the contrary, the "D" code 289CID engine eguipped with a 4 barrel carb were used on day one of Mustang production. The "D" codes were a low compression 210hp engine and the carbs were set up for that. The p/ns are C4GF-AE for MT cars, and C4GF-AF of AT cars. Note- the "G" means it was first used on a Comet.

Agreed.  The D code engines were of the 289 variety.  Low compression and I doubt the 4100 Motorcraft will fit that  intake.  Most likely he has a 260.

1964 Ford made a number of carbs for the 289 v4 coded C4GF, I think there 9 variations of the C4GF... C4GF-D, C4GF-E, C4GF-AA, C4DF-AA C4GF-AB, mostly used for Mercury or Comets. C4GF-AE, C4GF-AF, C4GF-AZ,C4GF-AB used by both ford and mercury.
And the C4ZF-C was used by mustang. And I'm not even going to list the Carbs for the HIPO.  But ford didn't always put a C4ZF-C on the mustang, It  kind of depended what was in stock or the installer happened to pickup at time of install I guess. The 4100 was used on on a number of 4 barrel intakes from 289 to 390  the only difference was basically the Venturi (1.02 or 1.14) and the primary jets and secondary jets but I'm not going into that. I'm pretty sure there wasn't an electric choke, but they did have a choke tube  with a heater hose mount next to the choke or a manual  but the manual was on the hipo. And some have dashpots depending on auto or manual transmissions

So the question would be.. since you have a C4GF is it orginal or has it been replaced?  Kind of depends on the last set of Letters. But if your not a die hard on originality just have your  Carb rebuilt.

Hope this make sense

One more thing, carb kits are cheap. think the last one I bought was $25 ish if your mechanical at all, you can rebuild it yourself

Glen,
  What is your obsession with a 260CID engine. There were only two 289CID engines offered for 64 1/2 Mustangs and the base number quoted was as follows:

All 4 barrel carbs used in 1964 were 4100 (the C4ZF-C was not well used, others were being phased out) and Kent did state C4GF type which is a 4100.
 Kent - either rebuild the carb yourself or have it done by a shop. The 4100 is probably the most reliable, gets the best mileage and preforms better than any other for a stock 289.

My obsession is that the 260 was the most common engine for the 64 1/2 Mustangs.  So, most likely he has a 260, depending on the build date.  In 1963 the 260 became the base engine on full-size Ford sedans. Later in the model year its availability was expanded to the Ford Falcon and Mercury Comet. The early "1964" Ford Mustang also offered the 260 as its' base engine, although it was dropped by mid-year.  Mid-year means August 1 of 1964.  With further research, I did find that Ford made an "F" and a "D" 260, but they both used the 4100 Motorcraft carb to power both of them, so I stand corrected.  So, my guess is that the 4100 will fit whatever engine he has in that 64 1/2.

Upon further review, any vehicle that had a 260CID engine with a 4 barrel carbs was installed by a dealer or the modifier. The latter includes Sunbeam Tigers, Cobras and Griffens. There were tri-power and dual quad setups available but the only factory carb on a 260CID engine was a 2 barrel.

According to this, the 260's came with either a 2V or a 4V 4100 carb.

This is very true plus any 260 in 1964 with a 4100 had, from your own source Soaring would also have had a aluminum (Shelby only) intake, solid & adjustable lifters (Shelby Cobra) and a manuel choke These 260 were made for the AC Cobra and Tigers. I'm almost postive just because of the C4GF it is a 289.  Once again there is no factory installed 4100 on a 260. My Source "Mustang & Ford Small Bock V8 Volumes 1 and 2"  By Bob Mannel

OK, I guess it is a moot point.  If he has a 289  "d" low compression engine, then he has a 289 that a 4100 will fit.  Problem solved.

Hi everyone,
     It seems the question about a carb for my 1964 1/2 289 Mustang has caused some discussion.  I have owned this vehicle since 1967.  It has the 289 emblem on each fender.  It has a generator.  It has a 1964 Ford Power steering system, Grease Zerts on the drive shaft, plastic door locks, etc.  And to top it off the warranty number etc. show it  a 289.  Here is the warranty # 5F08D126132 --- 76A  J  89  046   42  1  5
     Date 046, what does that mean?
     The vehicle does have a rally-pak, and I assume it was installed by the dealer, because I don't think they were available in the time frame of manufacture.  Any more information will be appreciated.

     Thanks for all the information on the carb.

Then you most likely have a 1965 low compression 289.  The Motorcraft 4100 is your best choice for that engine.

The "046" is "04E" by the VIN which indicates the car was scheduled to be built on May 4, 1964, and you are correct about the Rally Pac. Glen does have his act together about "most" carbs.
