Date coding
 

Should the date code of a holley carb. be dated to the engine build date or to the car build date on the vin tag?

Engine stamped dates were when assembled.
Chevrolet would dress the engines with a Carb. later on during cars assembly,so use the Cowl tag date as the latest possible date indicator for the Carburator stamped date.

Thanks Rick, I have been trying to find that out for a long time. There is about a 1 month difference in my motors build date and the trim tag date.
