    Ductile rocker arm hardware?
    « on: February 25, 2009 - 06:57:57 PM »
    Seeing that Crane is out of business got me thinking, I have a set of Crane Ductile rockers I'm going to use in my 440 build but I don't know what all it takes to use them. other than the normal rocker shafts and hold down kit do I need any springs or spacers or anything special I better be getting to use them?

    I would see if you can get a spare set of adjusters , some had problems in the past
    you need to use HD shafts , they are available from a number of places , nothing else is need to use them , they are a great rocker & Are virtually indestructable

    Is there a way to ID the HD shafts? the ones I have seem awful heavy to me but I'm not sure what they are.

    measure the ID at the end of the shaft where they plug goes in , I don`t have a stock shaft handy to give the spec sorry

    .60 ID, about .135 wall thickness, that tell anything? I don't have anything to compare  with.
