507 cam specs vs standard 09 c63
Is it true 507 c63s run a different cam spec compared to the first c63's produced (08/09 models)?
Thanks

Interesting. My tech said from 2010 part numbers changed. So I assumed cams changed too. I could be wrong hence why I started this thread. Thank you for the info though

I can't answer you question about cam specs but regarding part numbers, I often see them change while the actual component does not. At least the change is not percieved to our eyes.
Sometimes a PN change just means its coming from a different supplier.

I think only a couple top tuners can vary the cams.
Vtec can increase lift too. These don't, they can retard and advance each cam 20 degrees or so. Since its a dual cam head, the ECU can change the intake and exhaust relation as well.
I think the factory already has many many hours into the cams and has them running peak.
The cam variation is why the car idles perfectly but screams to redline with a nice broad torque curve.
