Cam question
It's all here: https://www.youtube.com/channel/UCkK...1PL8hhXfgttwMw
This same cam will be in my 2010 GS M6 by June.
I'd look for a cam with low overlap as overlap is directly tied to streetability. I'm running a 226/234 115+4. O overlap and perfect manners. Pulls really good on bottom and top end.
Better yet, Get Pat G's take on things. He doesn't miss.

A supercharger is a way better value upgrade than any cam.

C6 Z06 exhaust manifolds are actually shorty headers by design, so will be picking up about 15HP with them from a tune (will pick up another 15HP from the tune on the stock motor a well). Hence Bernoulli effect that allow more exhaust to be drown out of the heads by the shorty headers, and how you pick up the extra power.
Note, without tune, WOT will have the motor running on the lean side with the shorty headers.
As for cam, whole different ball game, and that is the way that the motor breaths instead. Some light cams just give the exhaust note some lob sound at idle, while radial cams can have the low rpms with so much surging, that the car is undrive-able in stop and go traffic instead.
Also,depending on how radical/how much lift the cam has, could be that you need to replace the lifters, rockers and even valve springs every 35K isntead.
Bluntly, unless you are in say CA and need to fly under the radar in regards to smog and changed parts, would be better off with Long tube headers with High flow cats, to pick up around 25hp isntead.
As for cam, yes, will pick up HP, but depending on what your going after, could remap the throttle to get you more instant power on demand, than how the TM and throttle mapping is holding that instant power back now. Hence have seen some C6's making huge numbers in regards to dyno's, but since TM is still in play to make that horsepower usable, the extra HP is really lost on say anything short a top end speed number where the ECM will allow all the power to be put down to the tarmac instead.
Simply, in stock form with a M6, could go into TM and throttle mapping on you your car, and change them so you could break the tires in any gear on street tires under 100mph. So would start with this, then decide is you want to throw extra power at the tires next, to just break them faster with less throttle push isntead.
