ok so i figured out most of it after some more scrubbin, the full stamp looks to be *99A834II3* which is 46' 69A ford or merc wont know more til i open it up, but the serial number looks from what i have found to be a restamp of what would have been *99A834113* however the block casting C564 does not show up anywhere i can find. C from some sources says Canada, but 564 is not one of the numbers.

Also the 99A in the serial says its a 69A motor, but the block clearly says 59 in a nice big stamp right on the bell housing? this is throwin me off and to boot the serial location is not following anything i can find as far as resources go either. every web site says the same thing, "serial number is not on the engine itself" but on mine it's right on the rear of where the intake mounts on the top of the block.

any ideas or help would be appreciated.
