911 SC's were produced from 1978 to 1983, with the 3.2 Carrera replacing it in 1984 (running to 1989)
SC's had the vaunted 3.0 motors, while the Carrera had the improved 3.2l motors. US horsepower difference was approximately 180 (SC) to 203 (Carrera) but the new Carrera motor had the pressure-fed tensioners that proved to be a great update for earlier cars.
The first Carrera's had the same 915 transmission as the SC's, but in 1987 Porsche introduced the hydraulic clutch G50 tranny, which is supposed to be a big improvement over the old trans. I've never driven it so I can't say.
Externally the cars are more or less the same with some minor visual cues. SC's had the front valence with driving lamps bolted to the front of it. Carrera front valences had integrated driving lamps.
There are lots of other little differences but the engine is the big one. If you want to learn more check out "Original Porsche 911" and "911 Forever Young"
