Help with engine i.d - Carreara 3.0 - Please
 

I have located an engine at a secondhand parts shop. The case stamping says 930/02 which I believe indicates a Carrera 3.0 and is what I am looking for, but the engine no. 6404993 makes no sense. Any ideas other than maybe a Carrera 3.0 with an incorrect number stamped into it for whatever reason? Does the Carrera 3.0 case have a different casting number to the later 3.0's that I can check out. The fuel injection, fan and alternator are gone but the motor has 3 pin CDI wiring and 2.7 type dizzy
rotation.

The Carrera 3.0 is either a 930/02 or a 930/12 (sportomatic).
The engine number should begin with 666 or 667 ('76 or '77)

Thanks George. The case is definitely stamped 930/02 but as I say the engine number makes no sense - from what I can make out It does not relate to any 911 motor. Any idea what the casting number on the crankcase would be for a 930/02 case?

Wayne bought one at Pomona last year and posted about it in this thread. Maybe he can pop in and tell you what #s it has, or PM him.

Wayne does the 3.0 Carrera case have unique casting numbers to help identify it if the incorrect engine number has been stamped onto it?

Robert

The 930/02 was the engine type #, as George indicated the '76 C3 will have engine serial #s 666**** abd '77 C3 will have 667****

serial # 640**** is a '80 US/Can SC type # 930/07. Its very likely the same casting # on the c/c is as on the C3

The 3 pin and 2.7 dist rotation is puzzling Is it posssible that someone tried to use a C3 dist on a later SC engine? This sort of thing was popular at one time.

The engine may have been a replacement ... and stamped with the engine serial number it replaced. Does the engine serial number begin and end with the '*' character?

The CDI and distributor are consistent with C3 Type 930/02 engine. Both '76 and '77 C3 engines used 3-pin CDI units and point-type 2.7 distributor!

Warren - Definitely no"*" with the number. I'm pretty sure its been stamped on afterwards. Also flywheel is 6 bolt pattern. Does this mean the crank must be a 2.7 or earlier and therefore the case must be a C3?

Robert

Robert,

Definitely ... more evidence that the Carrera 3.0 engine is genuine, and wayne's 'FAVORITE' ... as it used the 2.7 style crank with six M12 flywheel bolts!

Sounds like a winner to me!
