Engine Serial Number Query

[Etrain]

Hello, 

I have a '79 911 Targa. Trying to figure out two things: 

1>Decoding the engine serial number. It's 6291078

2>Should my VIN and engine number share the same numbers? 

 

Thank you!!

Also--where do I find my gearbox code? Thanks!

6291078 = 3 liter, 179 HP, type 930.04 engine - manufactured in 1979.

 

If it is the original 5-speed transmission then it should be a 915.61 - 5-speed gear box.

915.61 was used in 1977, 1978 and 1979 (for USA and Canada).

 

If it is a Sportomatic then it is likely a 925.16.
