I'm guessing it's a Curtis Sparks Racing re-grind that was made in May of 2002. I'd try calling them to check.

If you talk to them and it is their cam, ask them for the lift and duration specs. I've got a 400EX cam spec list and I'd like to add your cam to it.

ok thanks GPRACER it is a curtis sparks cam. It is there x4 cam which he said is a great cam that makes tons of power. Its a good mid-top end cam, but wouldnt give out teh specs on it. Its a hard face cam that needs heavy duty springs and hard faced rocers. So with that being said thanks for teh help.

I've never liked that CSR won't give out their cam specs...:ermm:

Glad you got it figured out.
