Marvin chose the PerTronix billet distributor for this project to enhance ignition reliability and enable him to fine-tune the ignition system. Coupled with the PerTronix Flamethrower ignition coil, it's unbeatable. When you use the Flamethrower coil, you must bypass the factory resistor wire from the ignition switch. Marvin has custom-curved this distributor for the customer's driving preferences. His curving technique also matches camshaft, heads, and induction.
