Identify this cam

[87_black_325is]

Only visible markings on camshaft through valve cover are, 204 and schrick.

Anyway to figure this out based on this?

I don't think that you can tell with only that info.

If you can remove the cam gear you should be able to see the part number which is etched on the flat end of the cam.

This link has part numbers as well as specifications which will help you identify it: http://www.turnermotorsport.com/imag...9_BMW_only.pdf
