Fully Adjustable Mechanical Advance

An important feature on all Top Street Performance Pro Series 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 Series 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.
