need stock adjustable rocker arms

Hi Wayne, I run the Crane rockers on my 71 Demon 340 stocker along with the MP chrome shafts. The stock rockers are all over the place as far as ratio is concerned. I also found the Sealed Power replace ones to also be all over the place. The Crane or Isky rockers are all right on with the 1.5 ratio. The pushrods can be made to the correct length by any one of the aftermarket manufacturers. Another good idea to add to the valve train are the MP billet shaft hold downs. Much stronger than the stock washer type pieces. Just my 2 cents from my experience over the last 30 or so years racing the 340 stocker.
