Are mods to the lifter retainer necessary? ? ?
Like the title says. Are mods necessary when using an after market cam? What is the max lift that can be used without having the lifter bottom out in the retainer. Also I have heard of a rev kit that helps keep the lifters on the cam lobe but have found no one who sells them. Anyone know anything about this mysterious rev kit? Thank for the help.
