Well I have my exhaust and open air box. I am guessing the next logical step is porting polishing and a cam Is this right? What kind of power gains can be picked up? I would be looking for mid to top end gains any particular cam? I probably won't be doing anything until winter but thought it would be real nice to have a good idea before then. Oh and if anyone knows of a good online store in the washington - oregon area please let me know thanks
