| Numbers on my new (old) marine 427's |

I am going over the 427 marine engines that I picked up in Maryland over the holiday, and although everything the former owner said appears to be true about the good condition, including new heads that were installed, I can not find any casting numbers on the blocks except for the designation 12 DIF.
The engines are cross bolted top oilers, but the location where I normally see casting identification is blank. The casting does not look like a side oiler casting that was machined as a top oiler, as I see no bulge where the bulge should be on the port side (driver side) of the motor. No tags on the motors, but they had been majored two years ago, with $5000 each spent on them. The blocks look pretty new actually, but looks can be deceiving. The guy said he thought they were 1970 motors, but this is word of mouth info.
I am wondering if they are replacement service blocks, and if so, how would I be able to tell with them still intact. Not that it matters, as compression and all signals are good. The heads are supposedly new, C7AE-A, which appear to be the generic 352 and 390 70 cc or so heads, not really too different from the C7JE heads found on standard marine motors.
Any clue as to the block. One last bit of info, the front motor casting (this is cast iron, and not a pressed metal timing cover) has a number on it, dating it to 1969, and I didn’t record it at the time as it was not directly attached to the block. This number may actually be of help and I’ll get it tonight and post it tomorrow.
Regards, P
