Ok.... I’ll try again. On the back of my 409 block. On the right rear side is the number. With the letter A. Information is appreciated.

409 dates are from 1961- early 1965. Then GM went on too build the 396 and 427.

So.... I guess this is pretty good. If your putting the 409 in a January - April or so 1962 it's a date correct 409 for the vehicle.

Any 409 is GREAT if the Block isn't cracked!!!!!!!!!!
