Help with identifying engine number
A buddy of mine just got an old 911. They guy who sold it said it had a 3.0L. The engine number is 6271659. Can anyone confirm? Thanks.

That looks to be a U.S 2.7 liter S engine for a 77 911. A 3.0 would have the numbers, 667XXXX if it was from a 77 car.

Yep, 2.7 engine from a 1977 Targa.

Yes and no. It's quite possible that the problems with the 2.7 had been addressed by the PO, and even rebuilt to 3.0 specs. No way to tell without further investigation. There is no reason why the engine may not be a solid performer. Identifying its origin is only the first step for a 32 year old engine.

Actually, I beg to differ. '75/76 cars were far more troublesome. '77 engines got aluminum timing chain housings, vastly improved valve guides, re-designed chain guides (ramps) and improved chain tensioners. O-ring and gasket technology also improved. The '77 car actually was a valuable link in the development of the SC, and '77 engines routinely lasted 100K + miles.
