Help me identify this engine please

[Hoegenauer]

Hello,

I have an engine from a 1974 911. Serial number is 6561043. Engine type 911/84. Case number is 901-101-102-79. Please help me identify. I think it is 2.7 California version, but what are the differences? What else can you tell me about the engine?

Thanks,
