HEI in Mopar ECU casing
I did it about 2 years ago. No problems so far. It starts way easier is the biggest thing. This thing has always been finicky about starting cold..either it didnt get enough fuel or it was flooded and had to pull and dry all the plugs. So far, its 100% better with this ignition. Like i said, it always took a lot of pumps of the throttle to get her started, but if you went a hair over what it needed, it flooded..not now!
