Something you might want to consider with camshafts for engines using LS3 and LS7 cylinders heads is the fact that the intake with the large 2.16 inch and 2.20 inch valves flows significantly more than the exhaust.
Recent testing done by companies close to the General show that on engines with LS7 heads, the exhaust duration should be 20 to 22 degrees longer than the intake duration.
With these cylinder heads, the days of just 4 degrees difference between intake and exhaust duration is over.
Also, LSA should be between 116 degrees and 118 degrees.
