Did you buy the cam already? If you didn't you might consider downsizing it a bit. You'll enjoy the car a lot more with some more torque.
The 5.3 is smaller than the 5.7 in your LS car. It will not react the same. It's also hard to keep compression high with the 5.3 util you get into milling a *lot* off the heads, which will bring it's own headaches. With that cam you're going to need a lot of gear and a 4k+ converter and valve to piston clearance may become an issue.
If you look at the specs of this EPS cam, it has far less duration and they're still calling for a 3500 converter and 4.11 gears as a minimum...

I think you'd be happier with this one, personally:
