    7,000+RPM drop in hydrualic roller lifters?

    Anybody have any experience with hydraulic roller lifters that will handle 7,000 rpm+? I understand cam lobe profile/ramp rate also play an essential part in contributing to valve/lifter float.

    Been doing some research and found these names Morel, Eaton, Sherman. Any experience with these manufacturers?

    I thought that eaton made the fms crane, & com cams lifters, but comp cams takes their's and adds a better spring & plunger to handle the rpm better, the comp cam lifters are suppose to be the best of the 3. They are suppose to be good to 7500 according to Jay Allen.

    No. I was spinning a 408 to about 6800. I ran solids. Call Anderson Motorsport. I think they have a high RPM hyd combo????????

    I'm running eaton's in my car Joe, but I don't see anywhere near the rpms you are talking about. I know these lifters are the same used in some pure street combos, but like you said, a lot has to do with the cam profiles.
