    US S50 M3 cams

    I have a line on a pair of S50 US M3 cams. How do I tell if they are genuine? Any markings I should look out for?

    Ask for pictures of the part number. Watch for scoring on the lobes, some scoring on the journals is ok.

      Sometimes it's better to pay a few dollars more and buy from a reputable person. Funkmasta especially. Really, unless I was a expert in a particular part, I would just get a part I know to be the real McCoy from a real seller who will make it right if things go south.

      It's not how you handle the good times, but the faith you keep in the bad that defines you.

        S50 cams

        Isn't there anyway to tell for sure that the cams come from an S50? To an untrained eye one set of cams look the same as any other.

          S50 intake is 1 738 369 the exhaust are the same at 1 718 888 and the M 50 intake is ? I gave you the number for a NV M50 intake sorry. Oh the Exhaust on the NV head is the same as the S50 cam.

              In between 1 and 2 on the exhaust and between 3 and 4 on the intake. Ask Trent for a picture of his M/S variant.
