How to tell a 3l Porsche 911 engine from a 2.7?
Discussion
911 SC 3.0 is from 1978 - 1983
2.7L has magnesium crank-case and a small ignition distributor with points.
Has 6 bolts on the flywheel to crankshaft.
3.0 has alluminum crank-case and a large ignition distributor with electronic (no points) distributor that has a green sheathed wire leading off the side of it.
Has 9 bolts on the flywheel to crankshaft.
There is also a 3.0 Carrera engine from the mid 70s which uses the 6 bolt flywheel.
Pull the distributor cap off and you will be able to tell, or at least, make a start in identification.

I think that the three litre engine will have a '930...' prefixed part number; whereas the 2.7l will have a 911 (or possibly 927) prefiixed number.
It was a 2.7 as it did only had the 6 torques fixing the flywheel to the crank and yes you are right the prefix for the part number does start with 911. And I have been told that the gearbox is probably a 915

Has everyone copied and pasted from the same website?
Without using Google I can confirm that the gearbox will be a 915 5 speed box this was used right up to the mid 1980's in to the 3.2 Carrera's.
The mid 1970's 3.0 engine was a normally aspirated version of the Turbo's engine. The Carrera 3.0 was aA great car, I owned one for many years.
