    My main issue with that cam is its huge for a stock headed older 5.3. Going over 230 intake duration in a 5.3 kills the power below 4500rpm you may have noticed the choppy nature of your torque curve. Now if you get some really well worked heads on it and 300 shot of spray then that's a great looking cam.
