My first mopar "stranded" moment with the HEI setup

The one that failed recently for me was a 4-pin DUI performance module.
I'm now using a 7-pin module, but I notice it still gets almost too hot to the touch when I let the engine idle in Drive (550rpm) for a while.
The cooling block also gets that hot so the heat transfer is good.

The module has its own relay so it gets full battery/alternator power @ 14.4v while driving.
