Engine numbers seem wrong

[Scotty4slr]

I bought a Holden 5ltr engine and I’ve been searching up the prefix and I can’t find out why my engine number is CVU614769. Why would it have a C? It looks original, it has roller rockers and they look standard, can anyone help me out with this engine cheers.
