My car came with a Mallory set up, Distributer, coil, and HyFire ignition box. The original builder had a rev limiter built into the dash.. It turned out that the rev limiter was to operate with distributer and coil.. So the rev limiter didn't work. When I redid Things I bought a newer version of Mallory ignition box that among other thing had a programmable rev limiter. That box crapped out during break-in
When the Mallory box crapped out it had a shorting plug that came with it that eliminated the box for testing and running with out the box. It was concluded that the Mallory box was to blame. The box was still under warranty so I returned and ordered another. It has worked flawlessly for twenty years now. I really liked the Mallory stuff. I was upset when I learned that MSD had taken over Mallory . Competition is a good thing. Why spend to improve with out any competition. My symptom was as I got farther from home the car would run worse and worse so I'd turn the car back towards home thinking it wouldn't keep running, but would idle just fine but getting the car t6 leave the light was terrible. But it idled just great
