Re: {Chrysler 300} AFB carbs / Edelbrock

Hello:

My name is Marilyn Reed. This is my first email to the entire Club as a whole, so please bear with me. After losing my husband last year, I am now the sole caretaker of our 1960 Chrysler 300f 413 cross rams. Prior to this it was my job to keep the car polished and looking pretty while my husband managed the mechanical side. I now have 2 questions.

I've been reading the conversation threads about rebuild kits for the Carter carburetor. I need two kits for my AFB #2903S. I saw the reference to The Carburetor Shop, so we called them about ordering 2 kits. We left a voicemail and are waiting to hear back. Does anyone have another source? I need to get the car on the road by August 23 for the Old 27 Tour here in Michigan. I have someone lined up to rebuild the carbs for me, I just need to find the proper kits.

Please don't laugh at my stupidity with this next question, but is there a tag somewhere on the engine that tells me if it's a 6.7L or 6.8 L? I know I have a 413; but when I search for parts, they want to know if I have 6.7 or 6.8L.

I would greatly appreciate any guidance you can offer. Thank you.

Marilyn Reed

For those of you with original Carter built AFB note that rebuild kits sold today use a neoprene or similar accelerator pump when the original is leather.

These non leather pumps never work as well and usually present a stumble that even an adjustment won't fix. There is a guy in the Corvette world, I'll find him, who sells a kit with the leather pump.

On 10 cars I've got at least 1 of every US carb built. The AFB, but for drying out too fast is the best carb ever devised for big cars.

The AFB was first used in late 1957 production Chryslers (not letter cars).

Here are pictures of my 57 Saratoga AFB compared to a 1966 version:

Carb i took off had the normal progressive linkage to secondary too.
