ignition coil ?

If you are running the car on 12V to the coil it will get hot. It should be running on 8 volts by using a ballast resister. Ign. 1 should be 12v to start. ign. 2 should be around 8V to run

The heat at the carb bowls can be decreased using a fuel return after the carb with a return regulator which is different then a pressure regulator. This keeps the fuel flowing and prevents the engine compartment heat from heating the fuel that is otherwise dead ended at the carb.

All newer carbureted mopars 85-88 used a return filter with 3 connections after the pump to do the same thing. But after the carb is much better.
