shimming hydraulic roller lifters solid

It's more than 10 hp.

This is an expensive hobby. $1500 is indeed a lot but prices are up on everything and this is no exception.

Solid rollers allow much more aggressive lobes and more valvetrain stability at higher rpms that hydraulic can't match.
K.. i didn't realize that solids used different cam profiles, thought it was just the lifter.. live and learn :)
