Need help with this ZL1 block

Have any members seen or know about this aluminum block with the extra rail along the drivers side bottom and it runs almost to the front of the block, dry sump maybe I don't know. Have a look at the pics, no numbers at all any place and it is a water block 427 ci overbore .030 and it's not like my 052 aluminum block.

Thanks

Here is my 052 ZL1 block without the oil rail.

We did a tear down of this engine and here is a better look at the rail, however I thought it was an oil rail but has turned out to be a coolant rail.
have a look.
