Engine numbers

[Thewizard]

Hi guys, Pretty new on the forum, Tried to search for a good source to decode a engine number code, i can't really find a good decoder.

My engine number is 6300705

Can anyone tell me some info about this engine?

Thanks

What year car?

630xxxx decodes two ways, either a 1970 S engine, or a 1980 SC ROW. The engine type number will tell which is which. The 1970 S will have a type number of 911/02, the 1980 engine will have a type number of 930/09.

Here's a link to a good source, but it's in German. Easily understood, however.
Porsche 911 SC - Modell 1978-1983

The S engine is 180hp at 6800rpm. The SC ROW engine is 188hp at 5500rpm.

Thank you for your reply, the engine number marking seems to be 930/09

Does this help?

The Engine also has a stamping that says 930/09.
