Re: 6.0 LS or build a 406?

As stated earlier a simple cam swap in the 6.0 can build amazing power with no other changes except tuning for the cam.
I am figuring on 425-450 hp so I was looking at SCAT or Eagle rotating assemblies and AFR 180cc heads. I thought anymore than that would be risky with a 2 bolt GM block but I know others would disagree.

Once I started adding it up, I got to thinking about the 6.0 swap. L92 heads and a cam swap put a 6.0 up to 550 hp according to Car Craft and that's way more than what I want or need.
