FBO's black HEI ignition box

RB,
Post #67, Yeah right, 2 amps, just what I said.....
You really ARE losing it. Now changing the goal posts...I gave the current ratings for both MSD coils waaaaaaaaaay back earlier in this thread, 1.1 & 2 amps.
If I am a battery fired ign loser, then I am joined by hundreds of millions, maybe a billion, across the world.

You lost the coil current argument, so now it's about spark duration of those coils; it hasn't suddenly changed to suit your BS.
