My 77 now has 200k on it and has started missing under full throttle at high engine speeds (above 4,000rpm). I replaced the Pick-up coil (in the distributor), cap, rotor and installed a new set of NGK plugs and changed the original coil to a Crane PS-20 with still no improvement. I was thinking of looking at the Ignition Module (under the passenger side dash) next, unless someone else has and suggestions.
