Cam Question

[Norton22]

Cam someone tell me what cam spec I have or where to find them I have looked but must not know where to look the number on the back of the cam is 242581 and has SP5 stamped in it. I just got the with a head I purched but dont have a clue what the RPM range is

thanks for any help

242 duration at .050.581 lift? On a 105 LSA? I assume the SP5 means special ground on a 105 Lobe Separation.Probably not a bad little light switch cam for a 7000 rpm deal. Low side range will depend more on what CR you are running.
