Merc 575sci Block Help

Im looking for a short-block to rebuild a 575. Couple of questions. Ive heard that the 575 and 525 block are the same, is this correct? Also, does anyone have a contact or source to find a replacement block? Thanks for any help!

Its just a Gen VI 502 block. The pistons in the 525EFI and 575sci are different and not sure what else in the shortblock.
