My buddy runs one, has for years.
I think is a comp, maybe crane.
300 or so duration narrow cl and .500'ish lift . w/11.2 comp on iron 915's
It's in a 4spd road runner w/4.10 gears and runs HARD
things fast and it idles like typical lumpy cam motor with all the 8 cylcle'n and such, but it idle below a 1000rpm no problem.
so I'm not sure what comp is talking about, unless they think you are going to daily drive it, even then whats the problem? do their lifter suck and break?
maybe think custom grind for what your doing, car,app, usage etc..
But honetsly, I have lil 1st hand in this topic of solid roller lifters on the street.
Personally, I see more moving parts in a hyd lifter, and more problems with them not pumping up...so.
So if someone here has actually run a solid roller themselves [we're taliking with todays roller lifters] and says no go then well....
