With that came you're gonna need around a 3200 stall. Believe me, I know from personal experience that the stock stall isn't going to cut it.
As far as the ls6 oil pump. You don't need it. If the engine has less than 50k miles you don't need to replace it but if it has more than I'd buy a new one. They're only like $70 from gmpartsdirect.com

I am running the stock stall right now on a 224 split duration cam and it is slow as hell off the line and continues to be slower than stock until around 2800-3000 rpms.
With that big of a cam, I would expect your 60' time to drop by 3/4 of a second, and your 1/4 time to drop by well over a second.
To answer your question though, it won't hurt anything but your pride. You'll feel like your cam swap was a waste until the engine revs to 3k rpms then it's like spraying a 100 shot.
If I were you though I would buy Thunder racing's cam package. It comes with
tr224 on 112 lsa, 918 springs, and hardened 7.4" pushrods. It is basically the same cam but for $100 cheaper. You don't need the double springs anyways.

This allows the truck to get in its powerband much quicker.
