Some engine block casting number overlap and multiple use is possible.

Engine block casting date codes begin with the letter "A" for January, "B" for February, and so on (the letter "I" representing the month of September was used) through "L" for December; followed by a digit, or digits, representing the date of the month ("1" through "31"); followed by a single digit designating the last digit of the calendar year. 

Small block (265, 283, 327, and 350 cubic-inch) engines were cast at the Chevrolet foundry in Saginaw, Michigan, and shipped to Flint for machining and assembly. Saginaw cast small block V-8 engines can normally be distinguished by use of a single digit calendar-year code; Tonawanda cast small block V8 engines normally use the last two digits (example: "62" for 1962), and these castings were not used in Corvette production except for the 1965 327 cubic-inch with 3858180 casting number.

Windshields, side door/vent glass, and coupe rear glass was LOF Safety Plate on 1953 through early 1971; Safety Flo-Lite beginning in mid 1971. No tinted glass was used on 1953 through 1962. Glass could be tinted or non-tinted on 1963 through 1969. Tinted glass became standard equipment in 1970.

Glass also carried the American Standard specification rating codes -- "AS1" for windshields, "AS2" for side door/vent and coupe rear glass. 1953-55 side vent and 1956-72 hardtop Plexiglas is coded "AS4", while folding top plastic back windows are coded "AS6".
