Start the engine, and allow it to run at low speed for a few minutes, while checking for leaks. Stop the engine, check the oil level, and fill as necessary. Restart the engine, and fill the cooling system to capacity. Check the point dwell angle and adjust the ignition timing and the valves. Run the engine at low to medium speed (800-2500 rpm) for approximately 1 / 2 hour, and retorque the cylinder head bolts. Road test the car, and check again for leaks.
Follow the manufacturer's recommended engine break-in procedure and maintenance schedule for new engines.
