224/230 duration at .050 is going to make a 5.3 lope considerably, and need a convertor for sure in a heavy truck.

I have a 211/230 LS7 stock cam in mine, when I did the DOD delete. it is noticeably light on low end power from 1500 to about 3500. Could use a convertor for it really to wake it up. So I can see how the 224/230 is really not what you were wanting for end results.
when you put the timing sprocket on, was it a 2x or 4x sprocket ? If the kit came with a 2x sprocket for instance (3 bolt), then the cam signal will not be correct. Your 09 should be using a 4x sprocket, with 58x crank. The 4x wheel has 4 raised bumps of different lengths on the front face of the camshaft sprocket. Sounds like you are going back in to change cams, when you get to that point confirm which one you have
