What is the full list of stuff you had done to the car? What aftermarket parts did you put in other than the cam? Any valvetrain work- 1.6rr's, springs?
Hmm, that actually leads me to a question for the lt1 guys here- can you run a cc305 with 1.5rr's and stock springs without trouble? I did a search on camaroz28.com and it seems like you can but I found no definite answer.
