What kind of open spring pressure would be needed for a 220/[email protected] .470 lift (1.5 rocker) HR regrind from Oregon Cam? Only spec Ken gave me is no more than 110 seat pressure. This would be on 308 casting head.

Why not call Oregon and ask Ken Heard?

Rusty I emailed Ken and he only gave me seat pressure. I covered that info in my original post.

Hydraulic or solid? I have a similar, solid-lifter camshaft @ Ken recommended 110-125 seat / 310-325 Open. That corresponds to this:
