Description:
These Pro-Billet dual pickup distributors from MSD are specifically designed for Circle Track racing. Not only do they feature a strong, CNC-machined billet 6061-T6 aluminum housing and a large steel shaft, but they also feature two magnetic pickups for a complete redundant ignition system that can be activated at the flip of a switch. The pickups are triggered as a precision reluctor, mounted to the oversized shaft, spins past. The pickups are placed precisely 180 degrees apart so that when you switch to the secondary ignition, the timing remains constant. Guiding the distributor shaft is the responsibility of two sealed ball bearings for incredible endurance and high-end stability. The shaft also receives a QPQ coating for corrosion resistance and friction reduction. Additional features include a fully adjustable mechanical advance consisting of a hardened advance cam, chromoly weights, and weight pins that are TIG-welded to the advance plate. The entire assembly is welded to the polished steel. The advance assembly can also be easily locked out for quick tuning changes. The Chevrolet model features two O-ring grooves at the base of the CNC-machined housing to prevent oil in the lifter valley from leaking through the oil passage. If the engine deck, heads, or intake have been modified, there is an adjustable slip collar that allows you to set the correct installation depth. All dual pickup distributors include a cap and rotor.
