It sounds like a head gasket.

those LT's are notorious for the distributor going on on them... when the intake starts to leak... it leaks straight down onto the distributor thats located behind the crank pulley.. pretty much starts to self destruct by shorting out...

Its probably the Opti-spark. They are the worst part of those engines, and some genius decided to put them under the water pump (which is prone to leak/go out to begin with-its the 2nd worst part!).

I would think opti spark too, especially if it is original to the car.
