The ls6 cam will produce more power but for the money you can usually get a better cam. With a cam that small the only other things you should look for are hardend push rods, valve springs rated for the higher lift and faster ramp rates and a new timing chain would be a sound invetment. If you do some searching you will find alot of previous posts on the matter.

I highly doubt you'd see a 40 rwhp gain. Maybe at the crank, but not way you'll see that at the wheels with an ls6 cam, unless you're boosted.

I have always heard 20-25 hp to the wheels with an ls6 cam on a 5.3l. So that could be around 35-40 at the crank. The LS6 cam does make a pretty solid boost cam. There are a few people running it and putting down some solid numbers.

I wouldn't bother with it honestly. Do you have any other mods to the truck?
