Holley Carb Ink Stamp decode
I believe the ink stamp codes on the bowls are for either the bowl or bowl/float assembly codes for manufacturing use on assembly. I have seen the same codes for different year carb bowls, so it would rule out a DATE code. The same goes for the vacuum diaphragm, spring, and housing assembly. Just my opinion. Don.

Reason: Addition of vacuum diaphragm assembly.
