GM HEI on Mopar,Does it work?

I run the "better quality" (translation: higher cost) NAPA HEI with an Accel "stock replacement" distributor (Mopar style pickup/ reluctor) and NO ballast. IT does NOT give up at 5500RPM, it's STILL cheaper and smaller than a Mopar, and easier to deal with wiring. I'm not sure of the origin of my stock--type coil, but I do NOT run a ballast.

I ran a Mopar ECU in about 73 right after they first came out---had a 340 swapped into my RR body. Ran it for a long time, but this was BEFORE the Chineseo replacements flooded the U.S.

In conclusion, my main motivation was simplicity and the poor quality of many parts-store Mopar ECUs
