Web Camshafts? or stockers is my other guess. If they dont idle like stock they are some form of a hardfaced regrind as the EP seems to be consistent thru all years of 4G63's

First thing I came to when I used just the casting number.

i am the second owner..after the dealer bought the car...they are not stock..i called crower today..they said that these numbers are the castings for the cores of the cams..then they do their grind to it...the guy said..they are definitly not stock..they are either comp, or crower..they are the only two that use these cam cores..it sucks that the only reason to tell the part number is to pull the cam gear off...since that is what is hiding the P#

Also stock Cams are hollow so u would know if thats what they are. I have Comp 272s that I bought from FP. I can help u anymore then what you already know. Maybe call Comp or Forced Performance. I def have small lope at idle even after a reflash and everything. the car never stall but u can tell there 272s
