Twin camshaft markings

Post by Marty »

Good evening. Can someone please identify that speedkit cams are marked SS. I have a set which appear 'lumpier' than others. Does anyone have a list of cam markings ?
Thanks, Marty.

SS was stamped on standard touring cams for 59 as it was the first year with the larger quietening lobes then dropped from then on. Speed kit cams were stamped RK
