lsj cam question
 

got a parts car, and I'm wondering what cams are in it, its a 06 ss/sc and they don't appear to be GM cams, and they are still in the car and the numbers I see so far are SJ 36n / SK07P / S363 / 3115 / 29-k / 8:50.
as far as i know GM cams say GM on them, so any input would be helpful.
