Ehgine Timing on 85 IROC with TPI automatic

My Vehicle Emission Control Label is gone from under the hood. Could someone let me know the correct Engine Timining setting. It should be printed on the label. All my repair books tell me to refer to the lable for the correct setting.

I believe that is for the L98. Not too sure about a 305.
