Can't believe your eyes? Look again. This Third-Gen Firebird features an '06 GTO's LS2 engine with a top end reworked by MTI. A Stealth II cam and Stage 2E ported heads from MTI are augmented by a Nick Williams 90mm throttle body, a FAST 90mm intake, a custom wiring harness and an '04 GTO ECM. Up front, a natural aluminum finish Be Cool aluminum radiator with dual electric fans keeps the LS2 at a 180 degree operating temperature. A K&N conical air filter connected to a custom 3 1/2-inch powdercoated black aluminum cold air intake provides plenty of incoming airflow. On a Dynojet chassis dyno, this '88 Firebird pulls a healthy 409 rwhp and 402 lb ft of torque.
