z129 block vs Z134 block

Does anyone out there know if a Z134 block will bolt up in place of a Z 129?

The back of the block is shaped different where it bolts to be transmission. It may partially bolt up, or it may not. They do use most of same internal parts.

They are the same pattern but there isnt a place for all the bellhousing bolts when the Z134 is mated to the transmission. That would make it a weak link.
