Running it on my non-mopar. 69 Cyclone with 351W. It runs great. I will admit I didn't do the set up on it and unlike the instructions, it took several weeks for the guy to get it running right. I went with the complete holley setup including distro to avoid issues. Not sure if it created or caused delays but before I did this, tried running 2 carbs on the thing and it ran like crap with a dead zone from 2500-3200rpm.
