I looked for a solid drop in style lifter and could not find one. I walked the PRI show and asked all the manufacturers. Jesel does make something but is big $$$. Comp does make a tie bar short travel lifter I installed in my new stocker engine, but I have not dynoed it yet. I do have the new T&D roller rockers and Smith Brothers push rods. I need something that can run to 8000 rpm.
