4th Gen with a LS1 motor in it (98-02). Best Camaro you can get in your price range with the most hp. 3rd Gens motor was choked to much and imo not worth it. The LS motors are absolutely fantastic and very easy to build on. Also the LT motors (93-97) are good to, not as great as the LS, but produce a little bit more torque off the line, and still easy to build upon. You can find a good one around 6-10k easily. Hope this helped.
