rocker arm ratio

  1. Adjustable rocker arm question

    Galaxie Pages
    I have a 390 with hydraulic lifters and cam. The stock rocker arm ratio is 1.73 and I want to replace them with adjustable rocker arms but all I can find are 1.76 ratio. Is this going to be a problem or will the slight difference in ratio going to work? Any help or suggestions is greatly...
