Racers and nostalgic Ford enthusiasts using the famous Ford FE engine now have access to a distributor that is truly equal to the performance level of their engine. A magnetic pick-up triggers your MSD Ignition control accurately at any RPM. Above this pick-up the mechanical advance assembly is positioned so it can be adjusted without disassembling the distributor. In addition, the specially ground advance cam is Tig-welded to the 9/16 In. hardened shaft and the weight pins are staked and Tig-welded to the advance plate.
