Calflows’s Pro Billet Ready to Run Distributor is perfect for a street performance ignition upgrade. It features a CNC-machined billet aluminum body and hardened steel shaft, with a sealed ball bearing on top and a sintered steel bushing on the bottom. It also comes with a fully adjustable mechanical advance, magnetic pickup trigger, a vacuum advance (not adjustable), and a high-output circuit board module with digital tach output. The dielectric cap comes with solid brass terminals and a color-matched wire retainer.

An important feature on all Calflow Pro Billet distributors is the fully adjustable mechanical advance. This allows you to easily modify the distributor to achieve a variety of timing curves. Included with all Pro Billet distributors are four bushings of varied size. The bushing determines the mechanical advance the distributor can achieve. Also included are six springs, with two at each level of tension. The springs control the rate at which the distributor reaches the advance.

What separates a Ready to Run from a Pro Billet is the top-of-the-line internal ignition module. Built using the latest circuit board technology, this module eliminates the need for external ignition control, such as a CDI box. It also comes with a digital tachometer output. With a Pro Billet Ready to Run distributor, just hook up your ignition coil, and you’re good to go.
