I am trying to spec a cam for my build. I am getting trick flow heads as well. What is the biggest cam you guys are running? I am not to concerned about a little low end bucking/surging. I am coming from a LS7 that had a 248/256 cam. I am not sure how big I can get away with on a 6.2 liter. What size big cams are you guys running? Any feedback would help. Thanks.
