All "SC" cams, be they on the Carrera 3.0l (76-77) the various SCs and the 3.2 use the same "grind". Porsche has changed the timing several times. Sometimes in the early 80's (I believe in 1980), Porsche changed the mounting system of the cam - which may explain the different part numbers (or not!).

Like you...not an expert, but I know enough to be dangerous.
