Hello 300’ly to all!
My C was manufactured 8/22/57 and has the modifications
to the carbs. This was verified last year when we rebuilt them and
replaced the carb floats. Vin 3N573216 with engine # 3NE573318. Rob

Yes, 58’s have the mods that the 57 service bulletin called for. That is
why 58’s have different carb no,s. Gary

Is it true that the 300D carbs are 300C carbs with this
modification ? (different Carter carb number, of course).

WCFB carburetors to address "stalling on turns"
Hi all,
I likely have one of few 300 C’s with factory modified carbs. My car was
built 2/25/57 and died in 70’s. I suspect Chrysler made the mods only if
customer complained. Otherwise they would have had to modify around 4,000
carbs if they did a re-call.
If the mods had been made, you will see 4 small holes drilled through the
outside of the air horns into the brass crossover tubes. Internally, there are
4 more machining steps to complete the mods in addition to changing jets and
rods.

Ray and all
I made the modifications to my WCFB carbs on my 300C postage stamp car
about 12 years ago along with the higher altitude rejecting that was
recommended. My mileage on 2 lane highways jumped from 14.5 to 17.3 between
Twin Fall, ID and Lake Havasu, AZ. Also solve stalling problem and rough idle.
I would highly recommend having done.

Hello to All -- Nuts! I Forgot that the 300
Club list server would not accept my attachment of the Chrysler Service
Bulletin 1034-CH on modifying the WCFB carburetors! So, if any
individuals are interested and cannot find the bulletin elsewhere
(maybe other members have that bulletin available, also), please contact me
and I will send it to you outside of the server! You will probably
still want to follow up on the jetting and metering rod recommendations to
make the modifications all work together. The 300 Club Forward Look
Archives contain my original messages from late 2012, as well as John
Chesnutt's listing of metering rod part numbers -- I used his p/n's to
provide the Carburetor Shop with the exact dimensions for the new (leaner)
metering rods and jets that I had Jim McGowan install. >
