What are the camshaft specs and ratios for the stock camshaft in 2006 Hummer H3

 

I don't know, are you planning on a custom ground cam?

 

I'm looking at upgrading the i5 for the vehicle I am adding a turbo to it and I was wanting to know if a cam would help I was wondering the lift ratios and specs of the stock and see if a performance cam would help/be worth it

 

I saw a supercharger for sale on H4O. Is that enough power?
