Hello crew! NES to the site, just bought a engine block from a guy wanted to know more on the block by these numbers, V05170TDR and C8A171530 any idea? I’m sure it’s a 350 but I could be wrong

Yup its a 350 might be a 3970010 casting but with that small number pad on the pass side front i'm gonna say its a 14010207 casting last of the 2 pc rear main seal 350 blocks
