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
