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" hardened shaft and the weight pins are staked and TIG-welded to the advance plate.
