Hey so had a question for everyone. I have a 75 911 targa S. The engine has been swapped the first 3 numbers of my engine serial are '659'. So it's a 6 cylinder, california engine, how can I be sure it's not an 89 engine? I'm assuming it's a 79 swapped into a 75 car?
This would be the 3.0 SC engine correct? I've read a little about these engines and hear they are good. Any insight on that?
Thanks
Derek

xxxx = Sequential serial number usually starting with 0001. Exceptions: Starting with 9001 = engine for Sportomatic.
X = 1, 911, Type 911/41, (or Type 911/46 for Sportomatic)
X = 3, 911S, Type 911/42, (or Type 911/47 for Sportomatic)
X = 4, 911S/Carrera USA, Type 911/43, (or Type 911/48 for Sportomatic)
X = 5, 911S/Carrera California, Type 911/44, (or Type 911/49 for Sportomatic)
X = 6, Carrera 2.7 (MFI), Type 911/83
X = 7, Turbo 3.0, Type 930/50
Best,
Grady
