How do you test the distrubotor on a 350?

To test the distributor on a Chevy 350 engine, first, ensure the ignition system is off and disconnect the battery. Remove the distributor cap and inspect for any wear or damage to the rotor and contacts. Use a multimeter to check the resistance between the ignition coil terminals; it should typically be within the manufacturer's specified range. Additionally, rotate the distributor shaft manually to observe if the points open and close correctly, indicating proper operation.
