Well im removing the motor to tear it apart to get to the bottom of this knock it has , well since it's coming out I might as well see if there is a better OTS cam for it, custom is out of the question because of funds right now and I don't need anymore downtime also, my current combo is: CHP 331 flat top pistons, AFR 185's, TFS stage 2 cam, TFS track heat manifold, BBK longtubes, 5-speed, deleted EGR, and smog pump. Is there a better OTS cam than the TFS stage 2 or should I just stick to what I have?
