    Performance cam ID

    Found out I've got a set of gs1150 cams marked yrd. St 1. Wondering if anybody knows for sure what they are. With 0 lash lift on the dial is showing right at 320 on both cams. Haven't measured duration yet took measure with a standard Gs1100 rocker arm

    Some photos of the markings would help.

    To measure is to know.

      In school I had a teacher who would give all the time you needed in a test. It was open book as well because that is the way the real world was. However, if you wrote a number down without units it was wrong and marked as wrong.

      Is 320 duration in Deg, Or milli radians of lash? How much the cams weigh in Deci-lbs? or what.


      1150 stock lift is Intake 0.315"(8.0mm) and Exhaust is 0.295"(7.5mm)

              I believe they were .335 lift & 248 duration.
