Delco coils
While searching the junk yard I noticed that most Delco ignitions burn the bottom coil
closest to the Rad. They all seem to have had replacements.
I was thinking of making a small heat sheild to redirect the hot rad. air away from the coil.
What do you guys think?

naw, the only thing that heat could be caused from is the lower radiator hose. and even then, i don't think we've really had any failures from this. i'm assuming you are talking about the delco ignition on your LN3, not the magnavox?

It sounds like a valid point to me. I would say that the radiator does radiate heat (might be why they call it a radiator, eh?), and could contribute to the more common failure of the front coil. I hadn't noticed that myself, but I've never looked.
There might be other factors involved, or it just might be a fluke, but it couldn't hurt to do a heatshield. You could even make it so that it would attach by sandwitching between the ICM and bracket, possibly. Just make sure it'* not going to cut into any wires.

Those same coils are found underneath the exhaust manifold on 60° V6 motors, which probably generates a bit more heat then a radiator hose, of hot air coming off the radiator. They don't seem to last any longer or shorter then the coils found on 90° motors, so I don't think there'* any correlation. From what I've read and experienced, you hit 100K miles + on ANY GM motor, and you're at risk of loosing a coil, or two........or three.
