I've looked for a chart that has all the square bore AVS part models listed, but I have had no luck finding this. What I am actually looking for are the models that had the two adjustment on the front, non emission models. Can anyone point me in the right direction, r tell me the best model numbers that were made in the larger AVS.

Thanks,
Tom

The Carter AVS carb that came on my 69 340 Dart 4sp was part# 4611s. It had the two mixture screws on the front.

4640s is a real good "750" cfm AVS. 68 and early 69 had the single LH top mixture adjustment. Then look for 440 HP models.

I have a question, why not a model with the 3rd mixture screw up top in the middle. It is an air bleed IIRC.

Yes, upper screw in post #5 is an air bleed......& LH thread.
The 340, 383 & 440 low perf AVS were all 625 cfm. My understanding is only the 440 magnum had the 750.
These AVS models were 750: 4428,9. 4617,8. 4637. 4640. 4737-41. 4967,8.
