Default 1970 and 1971 Z28 winters intake letter stamp meaning?
I have noticed on several 1970 Z28 #110 casting intakes and 1971 Z28 #594 casting intakes a letter stamp on the driver side center top of the intake near the base of intake. Was this letter only stamped on intakes used for warranty replacement to denote the month intake was put into service? Example: single letter "J" Would that be J for September? Anyone shed some light on this?
