i just got this cam off ebay and wanted to get some opinions on it. its supposed to be a speedpro roller with 224/224 duration, .496 lift, and 106 cam centerline. thats all i know about it. i am trying to decifer the numbers on it and will post what i find. does this sound like a roller grind? also dumb question, but what is the stock rocker ratio on tb's? guy says these specs are with 1.6 rockers
