Help to decifer casting numbers

[turbojitsu85]

I've been looking for a new block and found what I'm told is an 85 block but the casting doesn't match numbers that they have on gnttype.org. Casting number is 25524140?
Any help appreciated as always

The block is on the list. It is from a 1985 non-turbo Buick Regal. It is a twenty bolt pan and is totally interchangeable with the 1985 Turbo block.25520327. I put one of these blocks in my 1985 GN and had no issues what so ever.
