unless you are going to do head work, there is not a lot to be gained from a cam swap. it is $$$$ and a b!tch. this is why forced induction is so popular with the modular crowd, for the cost of ported heads, cams and intake mods or replacement,gaskets, you can have similar or better gains from a supercharger.
