Take off the front and rear engine covers and see if there is anything on the end of the cam. Looks like the Schrick cams in my motor. I have two different sets of scheicks that look very different, but when removing end cap to see numbers scribed on they have Schrick ID numbers on them. Remember they will not always look the same in pictures as what others have. Some cams could have been made in 1990 and some could be from 2015, chances are there are some visual discrepancies in that time frame. Manufacturing processes vary

not any number in front or rear of cam , this came from an early M3 , by the measures of the cam it looks like a 248
