never had a problem with mopar ignition, not even the lean burn deal but never ran a mopar on dirt! on a dirt track car i like the HEI for price and durability and simplicity and parts availability!
All I can say is, when "about" the only problem an ignition has is that it's so hot you need to carry a spare rotor because it burns through the center of them and GROUNDS OUT, it's a pretty hot ignition.
