according to the famous little white book written by the original "GURU" to whom you all worship the gentleman seems to be correct about his carburetor #6125 and its listed in the 1971 parts manual. huh? fancy that.

Can't help you, chum if you don't believe what I'm telling you. Holley R4668 carbs were put on Roadrunners with heated air intakes like I mentioned in a previous post. Mine never came with that option so I got the Carter AVS. Typical numbers found on broadcast sheets are fine for statistical purposes but they do not describe the rules for putting which carb on which car. FSM does.

OK let's see if this makes sense to you.

The FSM is a service manual. It's where you go to find out how to repair something or what the specs or settings are for something. It does not tell you what goes on what. For that they have a Parts Manual.



If you go to the parts manual. It's section 14-30-0. It shows that the Carter is only used on C Bodies. So yes there is a 383 AT Carter in 71 but it was never used in your application. It was used in the 330HP C body application.

My carb is listed in the link that you provided for the whole world to see now. Thanks for providing the proof, Bud. It's listed in model P,D,C (Plymouth, Dodge, Chrysler,) and Reference No. 114 and service carb # 3512844. If you open your eyes, you will see it. If not, I'll scan my chassis service manual when I get home later tonight that tells you why that carb is correct for my car.

The letters listed are for the car line and not just the model as is explained in your very own parts manual. P is Plymouth D is Dodge and C is Chrysler. This means all 383 4 barrel cars under that car line are subject to reference No.114. Now if only someone can decipher reference note 114 we would have the answer. Yes, I know that there is a reference to 2 Holley equipped Roadrunners up above with and without fresh air. Those are not mine because they have different reference numbers. If no one can answer that question about reference 114, I'll scan my chassis manual under the section about Carter AVS and Holley 4193A where it explains why certain cars came with Holleys and others with Carters.

These are the only 2 pieces of general information that you need to know to understand which 1971 Plymouth, Chrysler and Imperial that had 383 engines had which carburetors. It applies to all models across the board. Mine had the Carter AVS 6125S. I'm not the one asking for help with this. I never did. I'm the one who is trying to help you.

So When I see my friend with the 1971 Hemi Roadrunner, I'll be sure to mention that he should chuck his twin Carter AFBs in the garbage and replace them with Holleys just like you and the other misinformed individuals are suggesting right? No problem. Both the parts manual and the chassis manual are excellent resources of information. It takes no skill to read a chassis manual but certain training to read a parts manual. I am guessing that you simply don't have that training.

I thought we were discussing 383 4 barrels and whether they had a Carter AVS or a Holley.

Sorry I and others tried to educate you. Won't happen again .
