My COIL EXPLODED

Curious why you suggest this? All of the info in the directions from Petronix says use a 1.5 ohm coil.

Not arguing, just really curious.

A flathead is not a super high compression, high spark energy using engine. Higher resistance is safer on the Petronix and Stromberg electronic ignitions. Unless you run a extrmeme rotor and plug gap this will be just fine. I run a 3.3 ohm coil on customer cars without a inline resistor that have electronic distributors and have never had a issue. (personally I run points)
