Help identifying John Deere B43G long block

[jkerska]

Good afternoon, I found this block on an online auction. It seems to be similar to the 318 B436 engine block, I was just wondering if anyone on here could help reassure me or give me any pointers. Unfortunately the auction just states its an Onan long block. Thanks!!
