If this has been asked before, I'm sorry, and I know someone will probably say to use the search button, but, that's fine.

Anyways, I was looking up some performance parts for the Cobalt SC, and I read a thread a while back about GM Racing Camshafts, but, no one would say what the spec/grind was for these Cams, and I was wondering if the specs are as follows:

Duration @ 0.050" lift is 268 degrees on the intake and 268 degrees on the exhaust. Maximum lift is 0.464" for the intake and 0.464" on the exhaust. Lobe centerline is 232 degrees.

If this is the correct specs for those cams, could someone please pm me and let me know.

Thanks,

Island

The camshafts mentioned here
http://tunersource.gmblogs.com/blog/archive/2008/05/22/limited-number-of-high-performance-lsj-cams-available-from-gm-racing

Are discussed on page 14 of the pdf LSJ build book in chapter 6
http://tunersource.gmblogs.com/Racer-Tech/ECOtec-LSJ-Build-Book/ECOTEC_2.0L_LSJ_Chap_6.pdf

The Comp intake cam has the following specs: 0.441 inch net lift with 218 degree valve duration at 0.050 inch lift on 109degree lobe separation.
The Comp exhaust cam specs are 0.437-inch net lift with 220-degree valve duration at 0.050-inch lift on 109-degree lobe separation.

Thanks for the replies, but, would the ones I listed be any good? Or are they too similar to the 272's in that they are more designed for a Turbo setup?

Sorry for all the questions, but, there is no such thing as a stupid question, if you don't know the answer, :)

Thanks,
