Electromotive sells a DIS (4 coils, not 8). Some one on the list =
did that some time ago, you'd have to hunt the archives, unless he's =
still active.

Here's a mental project for anyone with extra time. To: anyone =
familiar with GM optispark units. As you know the whole thing is a =
pretty self-contained unit with a cap and rotor in a small, cam-driven =
unit and a nearby coil pack. The problem is LT1 water pumps die pretty =
regularly at 25-35k miles spewing dexcool all over the thing ruining it. =
They are not rebuildable, they have to be replaced in one extremely =
expensive unit. What about avoiding the time bomb altogether? I was =
thinking a crank positioning sensor and one coil for each cylinder a la =
Northstar or LS1. Will the computer signals be compatible with my =
stuff? I want to keep the stock computer setup, just plug and go.

Thanks,
Curtis
