The best (IMO). HEI module. buy or make the adapter plate. FBO advance plate. Radio Shack heat sink paste. E coil. direct 12V. no ballast. mod the dist subsystems in order: initial/total/springs/can. check/correct rotor phasing. buy (NAPA echlin MO3000 $8.XX) rotor that has a .060" longer brass blade tip or make a longer tip rotor (check your radial clearance first & .015" with no slop bushings is ideal). tan cap with ribs and add vent holes. check top flat plate pivot pin fit/slop. Pertronix is VG also EDIT (& the P system has caveats that need to be followed)
