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.
 
I just had a set of 308's redone locally. Used the trick flow #16514-16 single . Bigger than you need , 118lbs seat . Check out the trick flow single spring chart on their website , many to choose from .
 
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:
