How do I tell what year my block is? I mean I know how to tell but where can I find the chart for deciphering the code? Oh and I did .

 

if google doesn't know....nobody knows....

 

I found out how to find out the year model on a GM block. On the block at the front of the passenger side bank it a letter with a 3 digit # Example: I092 The letter represents the month of manufacture A= January B= February C= March and so on. The next two #'s are the day 09 is the ninth and the last number is the year. So my block was Manufactured August 9, 2002.

 

or call a GM dealer and give them the VIN

 

i want to say it was 99 00 model if its the block im thinking about
