coil without ballst resistor?

... As I pointed out earlier, a stock Mopar coil driven by a GM module, no ballast, puts out considerably more spark than the Mopar ECU. It "just might be" that most any cylindrical PERFORMANCE coil will "do ya" in good shape.
The ECU just tells the coil when to fire. The coil produces the voltage. The #8202 MSD coil I mentioned above puts out 45,000 Volts/140 mA. According to several sources (Google it) an OEM G.M. HEI coil puts our 40,000 volts.
