What's the cam specs?

If you're going to try and stay hydraulic, I'd ditch the link bar lifters, then run as light of valvetrain as you can....titanium retainers, locks, lightened lifters, etc.

I absolutely hate hydraulic cams for higher rpms. You can make them live at higher rpms, but it takes a little extra effort. For anything over 6000, I'd rather have a solid cam.
