I am familiar with block casting in Fords...however I am not sure if the same rules reach to Chevrolet.With Ford, they began using this form of block casting in the late 1950's. They assigned each decade a letter which begins the casting number. 1950 began the coding with letter 'B'. Each subsequent decade received the following letter. The first number after the first letter is the year of that decade in which the part was modeled for.This means that your block casting number D9AE-6015-ED-3 is for a:D = 1970's9 = 1979This piece has a block casting number for 1979.
