i wouls stay with the 224

 

I still can but can I ask why. The 224 works pretty good on my 5.3 but I thought it wouldn't be as good for the 6.0.

 

I say stick with the 224. I remember reading that you want more low end than your 5.3 has with that cam. If you re-use your cam in your 6.0 (which is 40" bigger) it should have substantially more torque down low while still having a strong top end. Basically I think your current cam will suite your purpose just fine and the money for another cam could be better spent elsewhere.
