Depending on what state your are in.. many times you are requred to pass the smog test for the year and type of engine you have swapped in.. here in Calif.. you would be re-cert'd to be the LS1 V8 (VIN of the engine/ECM).

But if you have a stock (or mid) tune.. and all of the equipement, you should be able to pass.

From what I have seen in IL they only care if you don't have a "check engine light" on. They don't use a sniffer here anymore. I had a 99 blazer pass with a hollowed out cat on it. It was reflashed to remove the O2 sensor.
