Well that wouldn’t really be practical as I have over 50 sets of carbs to go through. I just thought if someone could simply tell me what each placement represented I could go through them all. I didn’t get any response on the Z-II forum so I thought I’d try here in a separate thread.
As an example I have a matched pair with AM1 stamped below the list number 3361s

Okay. Well the AM1 would make sense as they are on my Jan Build ‘62 SS.

I’m not sure I understand the engineering revision reference. Would there be multiple revisions in a months time? How would one know exactly what that revision was? Is there a Carter AFB or Chevrolet production change memo? I look at a 3361 against multiple 3361’s and don’t see anything glaring at me.

Assuming you are correct and if it was week/month/year it would mean
A-D to cover weeks of the month
A-M excluding I for month
0-9 for year ?
As an example if I were to search for an early set of 63 carbs I would need something like A-D /J-L/ 2. (?)

Okay guys. Thank you for clearing this up. Does anyone know when the B code occurred? I’ll take a deeper look into my stash of carbs. I had a second set of AM1 carbs that were already restored in my shelf and just grabbed them to set on my intake manifold. Now I’ll go back and search for carbs closer to K-L2 for what I’m trying to put together for the Z-11 project.
