Honestly your 4.7L came from the factory with more HP then most 1999-2007 4.7L make modified...
The 2008 heads are completely different and so are the cam shafts. I also believe your 2008 cams are more aggressive then the older 4.7L engines. I'm not sure how they would stack up to the H/O grinds but Im willing to be they offer similar performance.
So at this time there are no aftermarket cams available for your 2008 4.7L engine.
