For demanding Ford racing applications, MSDs Pro-Billet Dual Pick-Up Distributors are the answer. Each distributor features a billet housing that is machined from 6061-T6 aluminum using computer controlled CNC machining technology. Additional features include a fully adjustable mechanical advance consisting of a hardened advance cam, chro-moly weights and weight pins that are TIG-welded to the advance plate. The advance assembly can also be locked-out with no welding. Two high output magnetic trigger pick-ups are bolted to the billet base of the distributor so you can have a secondary ignition trigger source for a backup ignition and coil.
