Engine Suffix Stamping Codes Menu

Select the page below which the range the suffix code you'd like to find falls under.  For example, select "DTR-HQ" if you'd like to find code DZ. In some cases suffix codes are reused twice or more over time, in this event check the block casting ID and then see what years the block ID was used to pin down what year block you are dealing with.

Note: CODE CE was used from 1968 to current year. It represents any CID and is used to indicate a Warranty Engine.
