Yes he'll need a timing light. Their is a brown connector close to the firewall on the driver side that will need to be unplugged (EST wire...1 wire connector) prior to loosening the distrubutor. Start the car, set the timing at 6 degrees BTDC and retighten the distrubutor. Rehook up the connector, undo the negative battery cable for 30 seconds to clear the code for the timing being disconnected and you are good to go. This is best done with a Helm (www.helminc.com) manual. Their is one for sale in the for sale section of the forum. Good luck!
