Review on 🔥 Enhanced Performance Pertronix D72000 Flame-Thrower HEI III 4 Pin Ignition Module for GM Vehicles by Robert Rasmussen

Wouldn't recommend, it didn't work as advertised, the rev limiter setting didn't work after a few tries even with it off, it popped and fired at 5200 no matter what I tried switched back to the stock module and my engine revs cleanly to 6000 with no problems. I changed the wires, checked the coil, the ground on the distributor, even slowed down the synchro. But it was just a defective unit, I was able to get a replacement for free but decided to just fit a half price replacement.
