Rusty, Early LS-1's mounted the coils on the valve cover, ie. directly on the engine.

Could the problem be due to high frequency vibration of the coils since Tracy has them mounted on the engine? (I know -- rotary's don't vibrate -- But they do actually, just less than recips -- but at a higher frequency?)

The 3rd gen RX-7 mounted the coils on top of the engine, under the intake, and they had a number of failures that were generally thought to be heat related. I'd have to bet the heat in that area on the stock FD was much worse than Tracy's 180 degrees. Does anyone know how the LS-1 coils are mounted on a Corvette? Do they get any cooling at all? I should have some of these on my truck, but can't say I ever looked to see how they were mounted.
