    yes they make them in 1.72 ratio (stock is 1.65) price is probably not much less than a grand for adjustable

    Done ,

    Ive PM'ed you just now.
    For a hydraulic cam setup, (standard) a non adjustable is normally used, if a big hydraulic or a small solid is going to be used an adjustable rocker arm is sometimes easier to setup for a big hydraulic and a must for solid.
