Cam setting and performance on 3.0l engines

[1100sport]

The C3 engine and early SC engines are pretty similar - same intake and exhaust, valve size, cam - with the notable exception of crankcase and crank (Indeed the c3 makes use of the light 2.7 crank). I do not believe that the difference in HP (200hp C3 vs 180hp SC) can come from the lighter crank.

However, C3 and SC do not have the same cam setting : Porsche set a milder cam setting for the sc in an effort to giver better low grunt.

So my question is: do you believe that the performance gap between c3 and sc engines come from cam setting ?

Is it possible to apply c3 settings to a SC engine ?

Partly, but there were also fuel and ignition mappings that were diferent.

The air pump used on SCs was also a drag on performance

and don't forget theC3 used a premuffler w/ an elegant internal shape, the SC used a cat

Lots of little things eventually add up

Can C3 tune be applied to SC absolutly, but I would lok at the '82 and '83 as a better model
