You may swap out your 2002 Chevy engine with a 1998 model, but it's not recommended. The State of California typically wants you to swap out with a newer model engine, but if you can make the job perfect by installing all the emissions components off of the 1998 engine, as well as ensuring all the electronics are working, you may be able to get an OK from the State.
After the swap is complete, your Chevy Camaro will have to be inspected by a California State Referee. The Referee will ensure that the job was done properly and that the new engine does not pollute. If all is well they will issue you a BAR label which will be placed somewhere on your vehicles chassis which will be an indication that the vehicle is California legal.
We highly recommend you speak directly with a State Referee before beginning any work, and get the fine details. You can contact the referee by calling (800)622-7733.
