I always hear the virtues of the HEI , here and on Youtube. But, I"ll go along with your comment.

Been running HEI for 5 years on a daily driver 70's Mopar without so much as a single glitch or no start.
I also built and sold LOTS of HEI conversion kits here, and any problem that kept the car from running was either an installation error or a problem with the car wiring causing low voltage, or the module wasn't grounded well.
