how far apart

    my original hipo engine was 1664, i have no date code, replacement is 1247 dated 5/14/63. can anyone tell me how far apart they are. thanks.

    Bob Mannel is keeper of the registry for the early hipo blocks. He has compiled a list of blocks with their assembly dates and sequential numbers. He would be the one to contact (he visits this forum often).

    1664 is close to the 1685 I have which was assembled 3H26. Next early one is 1443 dated 3F24 (late 63 production). Around 1500 was the 63 to 64 transition.


    Your 1247 has an assembly date code of 3E14, or a casting number of 3E14?

    That is a casting number. There is a stamped number on the block deck surface, all the way forward on the left side. It is right on top of the left water entry hole in the block. See if you can read those numbers. It tells you when the engine was actually assembled.
