To ensure no problems with the ignition system, Van Auken used an MSD billet distributor, coil, 6AL control box, and wires. Since this camshaft is a steel billet, it requires a bronze distributor gear, which takes some work to get correctly positioned on the camshaft for proper tooth engagement and shaft endplay with the distributor gear. Van Auken also made sure the thrust face of the distributor gear slightly lifts the shaft in the distributor housing, while not bottoming it out, so it doesn't inordinately load the distributor shaft top bearing. This is often overlooked on the Ford engine with dire results. To check this, the distributor gear is moved up and down on the shaft while endplay is measured. Van Auken found the total endplay was about .050 inch on this distributor and set the distributor gear in the block to split this distance. The coil mount was whittled out of billet aluminum. Notice how good the ARP fasteners look on this engine--a minor but telling detail that makes this engine look as good as it's going to run. View Related Article
