Engine emission control information labels are affixed to the radiator-support panel and provide specifics on some tune-up information such as ignition timing & dwell and idle RPM for a given engine/transmission application.

If you have a build sheet for your Chevelle, the label is coded in box 91 like this Kansas City assembly plant with the LS5 engine regardless of transmission type.
