With regards to the last post, if you race where overall lift is restricted, lofting the lifter at functional operating rpm range is one way to get competitive. It can be a little rough on the cam, as you can imagine. Get it right tho, and it can be worth a bit of hp.
Get it wrong, well let's just say it's not pretty

I've always believed, from what learned, the same cam grind in a solid will make more HP than a hydraulic grind will. The hydraulic may have more lift but the solid more HP. Also a solid RPMs better than a hydraulic.
technology and trial and error being in the millions of v8s.. roller is simply the winner.
there is along hill to climb sometimes... solid is like the hammer of a metal worker making anew shape, hyrdraulic goes through changes and stays alive.
I played with a boxer that shipped with all 3 designs.
never lookng back to solid/scraping hydraulic,not even with resto modding as a goal.Previously boxer3main
the death rate and fairy tales cannot kill the nature left behind.
