I always wondered if the person who ordered the truck was a bit wary of that "new-fangled" electronic ignition, and opted for the old mechanical type instead... I love the HEI system, I quickly went to a junkyard, paid $20 for a complete HEI Dist, and dropped it right in, just ran the hot ign wire from the old dist to the HEI "Batt" terminal. I crimped on a standard .250" female quick-connect, which slipped right onto the terminal. Spark plugs lasted twice as long, it started much quicker, and had more power & better throttle response. A Moroso centrifugal advance recurve kit, and an Accel HEI Super Coil finished things off for the ignition, never had to touch it for the 6 more years I had that truck.

thanks for that info.
I owned a 1973 impala with the 350 points distributor . plugs/points every 15,ooomi.
I just this year installed a pertronics point eliminator in my boat engine. with 2X the spark voltage and more effciency in the coil operation, the power,starting ease, and throttle response is much greater. more miles to the gallon .
I believe that the HEI system back then did the same on 2X of the ignition voltage.
