All original everything. L98 TPI 350 V-8 engine and transmission. I got it in February and started restoring it while I was in Miami. Replaced Fuel Pump, Fuel and Air Filter, EGR Valve, O2 Sensor, Idle Air Control Valve, Fresh Spark Plugs and wires, New Valve Covers and seals, Throttle Position Sensor, Fuel pressure Regulator, New fuel line hising under AC compressor, New Battery, Newer C5 corvette rims and rear tires, and I painted it in October. Drove it here to Atlanta in the middle of November. Been my only means of transport until a few days ago. Getting a knocking sound that I believe is a piston slap. Needs a rebuild to the rings or a new engine due to age. Car still starts and drives, I just know that its only causing more damage. Other than that the car isn't finished being restored. Things like carpet, dash, and other misc. things need to be done.
