For the next two versions of the 502, we added a Crane Fireball Hi-6 ignition system to the dyno. As power levels increase, the air/fuel ratio becomes more difficult for stock ignitions to fully ignite, making a quality aftermarket system a necessity. The Crane ignition works with the HEI distributor and includes such features as a built-in, adjustable rev-limiter and optional timing-retard controls.
