Solid lifter cams are for higher revs. Hydraulic lifters are not. Is that what you were trying to say? I hope so. A hydrualic valvetrain will pump up the lifters allowing the vavles to "float" and stay open when they should be closed. That's one of the reasons you won't see very many hydraulic setups on 5.0's turning more than 6000-6500rpms. I don't know if they even make a hydraulic lifter that can take 7000rpm for the 5.0.
