I was searching for ranger roller cam specs and ran across an article that discussed the differences between the 89-94 roller cam and the 95+ setup. Apparently the valve lift is the same on both cams but the 95+ cam has less lobe lift and uses higher ratio rockers to make up for it. Thus if you use the early roller cam with the late roller rockers you end up with something like 0.450" lift while maintaining the small duration numbers that make the ranger roller such a great cam for a street turbo setup.
Of course the late rockers are set up for the smaller 7mm valve stem so they need to be opened up a little for the early valve stem diameter. I'm dropping my head off at the machine shop soon so this is my opportunity to find a set of late rockers and have them opened up.
Anyone heard of this swap or can verify the numbers presented at this link?
