Thread: Late Rocker Assy Used on Early 322

  1. #1

    Red face Late Rocker Assy Used on Early 322

    OK...I read that interchange is acceptable on valve train components such as rockers, shafts, etc between a '55 322 and later, say mid '60's, nailheads, but is there any other component change affected that will require change/mod or ??? if said change is made? I've got a '55 322 that I am in the process of putting back together and have a late model rocker set with the pads on the rockers. Will the geometry of these (if used) require that I change pushrods, lifters or my mind? Or should I sell these suckers and opt for a new stock set and be done with it? I believe the difference is going to land between 1.5 and 1.6 lift or thereabouts and it should not make that much a difference with hydraulics...I am thinking. But then again...I am asking, so I am really not sure.

    Any help or advice would be appreciated. I have seen and collected Chevy bent pushrods before and have sets of valve stamped pistons from my childhood. Don't want any more such collectables.
    Regards,
    Gordon

    Yes you can. It will add about 10HP. One caution, you must check piston-valve clearance. There wasn't a lot of it before '56.
