MOPAR ECU Gold Box
I ran the Gold ECU on my car for over 3 years street/strip. Used the ballast that came with the electronic upgrade with orange box and with the big yellow accel coil. Both were mounted on the passenger inner fender close to the core support and very close to each other. Never had an issue and the 383 saw rpms to 7K and higher. It was the later 80's and perhaps the boxes were better back then. It was the best all MOPAR solution at the time IMO.
Going with the pertonix with my resto so I do not have to hide the gold ecu and harness. Hope the performance does not fall off to much, but don't expect to visit the strip so it should be fine.
