How much lift with stock magnum roller lifters?

Stupid question, be gentle...

What the aversion to hydraulic versus solid? Under pressure, the oil is damn near solid and doesn't compress right? I mean, I know it bleeds down but that fast?

I guess I think of it like the experiement kids do with corn starch and water. Add just enough water to a bowl of corn starch to saturate it, then poke your finger in. Goes right down to the bottom. now punch it, and it stops your hand acting like a "solid". In my head it seams similar in that the harder and faster you "hit" the oil, it's going to resist because of the viscosity?

BTW, with all of the talk I see about people wanting solid over hyd, I know I'm 100% wrong, but why?

Well.....the thing is, at high RPM, they cannot bleed down fast enough, so they cause the valves to float and hang open. That's when bad things happen. Conversely, solid lifters don't have that problem. The lash takes up and room at high RPM that would otherwise cause valve float and prevents it.

You CAN use a traditional anti pump up lifter. Those have a faster bleed rate at high RPM and will not float the valves, however, they require an adjustable valve train with a setting from zero lash, to around .002" lash, like a tight lash solid.

So, since they require an adjustable valve train anyway, the best thing to do is just go straight to a solid and be did wif all dat, yo.
