The ZR-1's ignition system is a kludge.  There is a flat ignition 
module that is mounted to the bottom of the plenum that sends 
signals to the coils, which are mounted right below the ignition 
module in the V of the engine.  Both of them get nice and hot 
because of poor (near zero) airflow - heat gets trapped under the 
plenum.  Yes, that means taking the plenum off to change plug
wires.

Just for completeness sake, the L98 uses HEI with EST.
