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.
