so i pulled the valve cover off my 03 evo...and ive been wondering what cams are in the car... i took a few numbers off of them but still dont know which cams they are...maybe someone can help me out...the part number is as followed

intake side C1 D5 EP4604 CWC
Exhaust side D1 D5 EP4604 CWc

that is typed in exactly how it is on the cams starting from the cam gear side...

ive done tons of search...alot of people have asked what cams these are but no real answers...

thanks

 

are u the first owner? coz my buddy bought 03 evo8. Original owner said it has JUN 272 Cams....when we open it....it was a stock cams only!!!

 

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
