I'm running a 350 chevy motor bored, stroked, and cammed with 2 four barrel carbs and a Mallory distributor and coil. Burned through 3 Mallory coils within 2 months. Put this one on it and haven't had a problem yet. The only thing that I seen wrong with it was it wouldn't quite fit in the Mallory bracket for my old coil. I had to grind the sides down on the coil to make it fit. Excellent price and excellent quality.
