Help with engine case numbers.

[porscheaddic]

I have what I believe to be a 1966 normal engine. Can someone please verify this. The engine numbers are 909782 and 901/05 and 6414. all help would be greatly appreciated.

Thanks

[19-911-65]

Per the "Red Book"...looks like a '67 911 coupe engine. 901/05 same as 901/01 except as of February 1966 Weber 40, not sure what the 6414 is??
