I replaced the worn-out Mallory dual-point in my 383 with the MOPAR electronic setup in 1989; I have run this distributor since then, with no trouble. Strong spark, easy starting, solid timing with no spark scatter, and I have replaced one ballast resistor. I switched to the epoxy-filled coil from the later 2.2/2.5 about 6 years ago, and only noticed a hotter spark from the system, no problems or weirdness. The orange ECU is the same one I installed when I converted from points in 1989, and it has been flawless. The spark is strong and the timing solid all the way up to 7000 rpm, and as stated, the parts for a roadside repair are readily available in almost any town in the USA.
