The gentleman that built this motor noted that it was a sissal-moon cam. I think this motor sounds tremendous and thought I might like to try copying the headers, intake and use the same cam. I don't think Moon grinds cams any longer as their long time grinder either retired or passed. And I am not 100% positive that Mike Kirby is still operating the Sissal shop so dont know if that is an avenue for a cam, but I think I will check with Schneider Cams and see if that is enough information to grind a "Moon" cam copy.
