I'm not an expert by any means, but everything I've read suggests that if
you're going with forced induction you're better off with a stock camshaft
instead of a high performance cam. As I understand it, with the
supercharger forcing the charge into the engine you don't need the extra
duration or valve lift to feed it, so you're basically giving up low end
smoothness and torque for no reason. I suppose a cam grind with stock
intake lobes and performance exhaust (the supercharger doesn't pull exhaust
gas OUT of the cylinders) lobes would be an improvement, but I've never
heard of anyone doing that.

station wagon)
