camshaft help

I need help identifying the cam in my dads motor. there is no numbers on the ends of the shaft. Only thing I can see is the purple/blue end, and a purple stripe by the lobes. The cast numbers by the lobes is SCH 7658 if that helps. Was always told was a 509 cam. Tore motor down and needs complete rebuild. UGH... email sixbbl69@hotmail or PM me. Thanks Jason

509 gross lift divided by 1.5 rocker ratio is .339 at the cam. Mike the cam & subtract the base circle from the lobe height to get the lift and see if it's .339".
