dont bother with the VS or S1X cams... go straight to the biggest cam for stock heads which is the XP. If its tuned properly you will not lose any bottom end torque.
You will regret not having gone a bigger cam if you put the VS in... trust me. I even wish I'd gone bigger than XP and got headwork done etc...
When I got my XP cam done and tuned it idles like a stocker and to be honest if someone would have come into my garage and secretly done it overnight without my knowledge I wouldnt even have noticed it... until I step on it and go over 3500rpm that is
So basically drivability is exactly the same only with much more mid- and top end power than before... (I had 1.98 modded rockers on before)
