In the early 70,s we only had points and crappy wires. If you drove your car on the street a while the misfire around 4500 started. We called it (busting out). Fresh plugs, and I mean fresh would straighten it out. We carried a new set for money street races. Someone had a spark plug sandblaster that helped a lot, small unit with a grommet hole for the plug. Then came Accel points and the big yellow Accel super coil the hung on the firewall. You also have to remember the tune up intervals when cars had points. When HEI started the selling point on new cars was no tune up for 20,000 miles. I think some guys might have weak coils but some just have original equipment old cars.
