    Iskenderian will grind a cam for your engine. They have what they call an E4 or an ST5 grind. I have an ST5 cam in my Avanti and it works really well though the idle isn't the smoothest, but the exhaust sounds good. The E4 will give you a smoother idle and I believe is better suited for an engine with stock compression and higher rear end gear ratio. You will have to send a regrindable core to them as new cam blanks are no longer available. Bud

      Get ahold of Phil at "Fairborn Studebaker".
      He should have all the info you desire...including cams, ready to go.

        Here are some links to some R series data. Sorry I don't have it in better resolution, but it should be readable.

            FWIW, for anything approaching street use with stock heads, the standard R1 cam can't be beat. After the first $2,000 in pro head work and a custom intake, then big bucks cams earn their money.
