I found some ignition coil data on Jim Lux's website and plugged it into my 
PSpice simulation. The ignition coil secondary would be dissipating about 
50 to 60 watts of heat. The power loss isn't a problem in my system, but if 
the coil overheats and bursts it wouldn't be too good. As for the 
inductance: I know more is better but I understand that too much will 
eventually mess up the performance at the high end. I'm going for 400bps, 
20 to 30 Henries is about right for my system and if I can get that from a 
couple of MOTs that would be great.
