Block identification number generally on side of block above oil filter for blocks cast at Cleveland. Dearborn block I.D. number near distributor and above generator. Most Dearborn blocks used in trucks. No Dearborn blocks after 1957. There were no special truck blocks. Heavy duty trucks with steel cranks used C1AE or C2AE car blocks. Nearly all Dearborn blocks after 1954 were 272's. Most 292 and 312 blocks are from the Cleveland foundry. www.ford-y-block.com
Thanks for posting this. This looks fairly inclusive of all the Y-block stuff. There were so many different ones before and after the MEL & FE blocks were produced. Most folks look at a Y-block and think it is either a 292 or a 312.
