Title: 4100 Autolite Carburetor code
Post by: austr6 on October 25, 2015, 06:23:50 PM
Hello, I have a question relating to a carby on my 66 GT A code. It has a code on the base stamped into it that reads  C6AFAA. I cannot determine what this carby was on originally, or if it is the correct carby for my vehicle.
if any one can help that would be great.
Please let me know if you require any more info.
Thank you.

By the numbers posted appears to be a replacement and not original to your car.

Books show a C6AF-A as an original for a full size car's 289 4V carb with a manual trans

The part number in question and answer don't match. C6AF-AA is a 2100 for a full size Ford, AT and smog. C6AF-A is 2100 for a full size Ford, MT, no smog. Go back and look at the base and ask again.

Thanks. Checked again and yes I had the 2100 page rather than the 4100 one :(   

That's why the group effort really works :)

This carb is a four barrel... I'm very new to ford stuff, but I was of the belief that the 2100 was a two barrel carb?
And what is a full size ford?
Thanks again

LTD and Galaxie would be two examples of full size Fords

can someone please then let me know Exactly what carby i should have on my car so i can source the correct one, the vehicle is a 66 GT A code fastback (6R09A202931). DSO  712887 (was a special order paint vehicle, hence long DSO)
I need to know with 100% certainty.
Thankyou

Sure. It should be a C6ZF either a -D for a manual transmission or a -E for an AT. It is determined by transmission. Note the "Z". Your DSO is Los Angeles so you get a smog carburetor, with the appropriate smog stuff. Non-smog are a -A for the MT, and a -B for an AT. The -C and -F are used on 66 and some 67 289 HP engines, plus most of Shelby GT350H's. 
Jim
For the record, where are you in Australia? You got a lot of "mates" on the forum.

I am almost certain I have a restored C6ZF-D (manual with Californian smog) and also a unrestored C6ZF-E (automatic with Californian smog) in stock at present.

so both bases are covered, drop me a email; outlaw@hn.ozemail.com.au
and I will send you pictures and information.

Thank you Phill, i will record your email details and will be in contact.
One more question, does it absolutely 100% have to be a smog equipped car as there is no evidence of smog equipment ever being fitted to it???

What is your cars DSO? This might help with the smog question.

According to search and research the C6ZF-B Excluded TE (thermactor Emissions)? Someone here know something different?

Also, what Mustangs received the C6ZF-B carburetors?  A codes?
Thanks

I believe the correct code for TE and automatic trans should be C6ZF-E. The C6ZF-B would indeed be for an "A" code car as this denoted a 289-4v car, with an automatic trans (non-TE).

That is what the Carburetor Guide shows

So does that confirm my thoughts that my vehicle was not equipped with the smog stuff?
it is an A code 289 4V with factory air conditioning and factory power steering.
By the way, a big thank you to all for your help and knowledge.

Not sure if the carb alone would be a good indicator. Guess you don't have an original door tag or heads on the car

Indicators like thermactor heads, alternator brackets and such can all help. Know where the car was sold or what district are likely the best indicator IMHO

I have the door plate and the DSO was 71 but i believe the car was ordered to send to Arizona? I will look at the heads once i have a spare minute to remove the rocker covers i will get back in touch with details

The DSO would be 75 if it was an Arizona ordered car. All 1966 Fords ordered with DSO 71 and 72 were required by California law to be equipped with smog equipment. (The same smog equipment applied to all new 1966 cars from all manufacturers.) There are a couple of "quirks" in the law which states "sold in California after January 1, 1966", but Ford put smog stuff on all California cars from August, 1965 anyway. For some reason, 66 HP engines were exempt as well (thankfully).

Your VIN indicates a May, 66 build which may (pun not intended) have one of two types of smog heads. The early type have an air injection port for each cylinder, and would be obviously "plugged". The type used in 67 has a single port at the LH rear or RH front. I'm not sure if the 67 type can be made non-smog, a "plug".
At this stage, you might want to verify the engine assembly date. It's located on a casting extension, called a boss, on the LH front side near the distributor. A bolt from the water pump goes into the "boss". The format is, year (single digit), month (a letter), one or two numbers for the day, and a letter, assembler or inspector. Yours should look like "6CxxZ" or "6DxxZ".

There are some exceptions to that practice but they are very very few and would require additional documentation to be believable IMHO

So few that they become legends. Have you, Jeff, seen any? Well, it's close enough to Halloween to qualify as a "ghost".

Most memorable and easier to document are a very few 67's. But have seen a couple fo the 65-66 though would still go by the DSO for a guideline for 99.8% of the production.
