Thanks. Taking your cue, I found them for $42-43 at autopartsgiant.com and
just ordered a set of 6. I will probably get Magnecor to make a custom set
of wires for me with the LS1 coil ends and the Probe plug boots.

I'm getting ahead of myself, though. Do you know the pinouts for the coils?
Since they contain their own drivers, is the trigger +5V? +12V? I presume
it's
still a square wave: +V to begin charging/dwell, 0 to fire. I haven't seen
any specs on these coils, aside from a May 29 1998 posting on this list from
Garfield. This will really tweak my switching strategy...
