Question about blocking hyd. roller lifters

[Mike Taylor 3601]

You can also put solid rollers on the hyd.roller cam if you aren't restricted by rules.You'll want to keep lash .008 or less if you get over .008 it will beat on things bad,the solids are lighter you'll gain some rpm and pickup torque. Most of the stocker hydraulics have .015 of travel left in plungers.
