I currently have a mostly stock '99 ls1 motor. The only thing that has been changed are the rockers. They are Harland Sharp 1.8's. They NEEDED to be changed (Spilt bearings on the stockers). I DO NOT intend to change the rockers again. What cam can I run in "The Peoples Republic of California" and still pass SMOG

? I will also be changing the springs, as I understand this is a must. Probably 918's or what ever is recommended for my application. I would also like a guestimate for total cost. I will have Don Lee Auto do the work since they did my rockers.

Don Lee Auto

Any recommendations will be appreciated. I have used the search and found some information. Just looking for clarification.
