How much actual power/driveability difference between COMP 224-228 cam or 228-232
I will probably be going cam first,then possibly heads (PRC or Livernois STG 1 LS6)later.I want a stealthy idle/and need to pass SMOG in CALI so I will go 114 LS or 116,and I guess have some ADVANCE ground in to bring the curve back in line .Which one is better and how more power will the 228-232 make at what cost to driveability with mods in sig?

Most people agree that -5 degrees overlap is the max that will still pass. That said, a 224/228 cam needs a 115.5 LSA to get there, while the 228/232 cam would need 117.5 LSA. At that wide angle, the intake valve is closing very late, and the exhaust valve is opening very early. The VE's really fight the rest of the engine tuning. That is just too much cam to pass emissions, or to be stealthy for that matter.
