My combo

What I see odd is the more lift on the intake side. That's radically differemt than anything I've seen or used. You cant tell anythign more wihtout real specs. Duration at .020 ans .050 would help, as will the figuring at 1.5 or the 1.6 you run. You can only lift so fast with a hydraulic roller, so it cant be too radical. But if the durations up there, you should make ok power. Normally, you see cam grinders giving more lift and duration to the exh side on a split duration cam. All that cam would do on most heads is realy hurt the intake to exh ratio. I dont think it would do much to help power, unless the entire exh system was extremely good at it's job. That's why I think you may have the specs right, but the sides wrong...lol.
